2012.55 - Wednesday 22 February 2012
- Security: Fix use-after-free bug that could be triggered if command="..."
authorized_keys restrictions are used. Could allow arbitrary code execution
or bypass of the command="..." restriction to an authenticated user.
This bug affects releases 0.52 onwards. Ref CVE-2012-0920.
Thanks to Danny Fullerton of Mantor Organization for reporting
the bug.
- Compile fix, only apply IPV6 socket options if they are available in headers
Thanks to Gustavo Zacarias for the patch
- Overwrite session key memory on exit
- Fix minor memory leak in unusual PAM authentication configurations.
Thanks to Stathis Voukelatos
- Other small code cleanups
2011.54 - Tuesday 8 November 2011
- Building statically works again, broke in 0.53 and 0.53.1
- Fix crash when forwarding with -R
- Fixed various leaks found by Klocwork analysis software, thanks to them for
running it
- Set IPTOS_LOWDELAY for IPv6, thanks to Dave Taht
- Bind to sockets with IPV6_V6ONLY so that it works properly on systems
regardless of the system-wide setting

to accounts with a blank password. Thanks to Rob Landley
- Fixed case where "-K 1" keepalive for dbclient would cause a SSH_MSG_IGNORE
packet to be sent
- Avoid some memory allocations in big number maths routines, improves
performance slightly
- Fix symlink target for installdropbearmulti with DESTDIR set, thanks to
Scottie Shore

0.53.1 - Wednesday 2 March 2011
- -lcrypt needs to be before object files for static linking
- Compile fix when both client and agent forwarding are disabled
- Fix DROPBEAR_PRNGD_SOCKET mode
- Don't allow setting zlib memLevel since it seems buggy
0.53 - Thurs 24 February 2011
- Various performance/memory use improvements
- Client agent forwarding now works, using OpenSSH's ssh-agent
- Improve robustness of client multihop mode
- Fix a prime generation bug in bundled libtommath. This is unlikely to have
generated any bad keys in the wild.
See
https://bugzilla.redhat.com/show_bug.cgi?id=615088
http://bugs.gentoo.org/show_bug.cgi?id=328383
http://bugs.gentoo.org/show_bug.cgi?id=328409
- Attempt to build against system libtomcrypt/libtommath if available. This
can be disabled with ./configure --enable-bundled-libtom
- Make -K (keepalive) and -I (idle timeout) work together sensibly in the client.
The idle timeout is no longer reset by SSH_MSG_IGNORE packets.
- Add diffie-hellman-group14-sha1 key exchange method
- Compile fix if ENABLE_CLI_PROXYCMD is disabled
- /usr/bin/X11/xauth is now the default path
- Client remote forward (-L/-R) arguments now accept a listen address
- In uClinux avoid trashing the parent process when a session exits
- Blowfish is now disabled by default since it has large memory usage
- Add option to change zlib windowbits/memlevel. Use less memory by default
- DROPBEAR_SMALL_CODE is now disabled by default
- SSH_ORIGINAL_COMMAND environment variable is set by the server when an
authorized_keys command is specified.
- Set SSH_TTY and SSH_CONNECTION environment variables in the server
- Client banner is now printed to standard error rather than standard output
- Capitalisation in many log messages has been made consistent. This may affect
scripts that parse logfiles.
0.52 - Wed 12 November 2008
- Add "netcat-alike" option (-B) to dbclient, allowing Dropbear to tunnel
standard input/output to a TCP port-forwarded remote host.
- Add "proxy command" support to dbclient, to allow using a spawned process for
IO rather than a direct TCP connection. eg
dbclient remotehost
is equivalent to
dbclient -J 'nc remotehost 22' remotehost
(the hostname is still provided purely for looking up saved host keys)
- Combine netcat-alike and proxy support to allow "multihop" connections, with
comma-separated host syntax. Allows running
dbclient user1@host1,user2@host2,user3@host3
to end up at host3 via the other two, using SSH TCP forwarding. It's a bit
like onion-routing. All connections are established from the local machine.
The comma-separated syntax can also be used for scp/rsync, eg
rsync -a -e dbclient m@gateway,m2@host,martello:/home/matt/ ~/backup/
to bounce through a few hosts.
- Add -I "idle timeout" option (contributed by Farrell Aultman)
- Allow restrictions on authorized_keys logins such as restricting commands
to be run etc. This is a subset of those allowed by OpenSSH, doesn't
yet allow restricting source host.
- Use vfork() for scp on uClinux
- Default to PATH=/usr/bin:/bin for shells.
- Report errors if -R forwarding fails
- Add counter mode cipher support, which avoids some security problems with the
standard CBC mode.
- Support zlib@openssh.com delayed compression for client/server. It can be
required for the Dropbear server with the '-Z' option. This is useful for
security as it avoids exposing the server to attacks on zlib by
unauthenticated remote users, though requires client side support.
- options.h has been split into options.h (user-changable) and sysoptions.h
(less commonly changed)
- Support "dbclient -s sftp" to specify a subsystem
- Fix a bug in replies to channel requests that could be triggered by recent
versions of PuTTY
0.51 - Thu 27 March 2008
- Make a copy of password fields rather erroneously relying on getwpnam()
to be safe to call multiple times
- If $SSH_ASKPASS_ALWAYS environment variable is set (and $SSH_ASKPASS is
as well) always use that program, ignoring isatty() and $DISPLAY
- Wait until a process exits before the server closes a connection, so
that an exit code can be sent. This fixes problems with exit codes not
being returned, which could cause scp to fail.
0.50 - Wed 8 August 2007
- Add DROPBEAR_PASSWORD environment variable to specify a dbclient password
- Use /dev/urandom by default, since that's what everyone does anyway
- Correct vfork() use for uClinux in scp
(thanks to Alex Landau)
- Exit with an exit code of 1 if dropbear can't bind to any ports
(thanks to Nicolai Ehemann)
- Improve network performance and add a -W <receive_window> argument for
adjusting the tradeoff between network performance and memory consumption.
- Fix a problem where reply packets could be sent during key exchange,
in violation of the SSH spec. This could manifest itself with connections
being terminated after 8 hours with new TCP-forward connections being
established.
- Add -K <keepalive_time> argument, ensuring that data is transmitted
over the connection at least every N seconds.
- dropbearkey will no longer generate DSS keys of sizes other than 1024
bits, as required by the DSS specification. (Other sizes are still
accepted for use to provide backwards compatibility).
0.49 - Fri 23 February 2007
- Security: dbclient previously would prompt to confirm a
mismatching hostkey but wouldn't warn loudly. It will now
exit upon a mismatch.
- Compile fixes, make sure that all variable definitions are at the start
of a scope.
- Added -P pidfile argument to the server (from Swen Schillig)
- Add -N dbclient option for "no command"
- Add -f dbclient option for "background after auth"
- Add ability to limit binding to particular addresses, use
-p [address:]port, patch from Max-Gerd Retzlaff.
- Try to finally fix ss_family compilation problems (for old
glibc systems)
- Fix finding relative-path server hostkeys when running daemonized
- Use $HOME in preference to that from /etc/passwd, so that
dbclient can still work on broken systems.
- Fix various issues found by Klocwork defect analysis, mostly memory leaks
and error-handling. Thanks to Klocwork for their service.
- Improve building in a separate directory
- Add compile-time LOG_COMMANDS option to log user commands
- Add '-y' flag to dbclient to unconditionally accept host keys,
patch from Luciano Miguel Ferreira Rocha
- Return immediately for "sleep 10 & echo foo", rather than waiting
for the sleep to return (pointed out by Rob Landley).
- Avoid hanging after exit in certain cases (such as scp)
- Various minor fixes, in particular various leaks reported by
Erik Hovland
- Disable core dumps on startup
- Don't erase over every single buffer, since it was a bottleneck.
On systems where it really matters, encrypted swap should be utilised.
- Read /dev/[u]random only once at startup to conserve kernel entropy
- Upgrade to LibTomCrypt 1.16 and LibTomMath 0.40
- Upgrade config.status and config.guess
0.48.1 - Sat 11 March 2006
- Compile fix for scp
0.48 - Thurs 9 March 2006
- Check that the circular buffer is properly empty before
closing a channel, which could cause truncated transfers
(thanks to Tomas Vanek for helping track it down)
- Implement per-IP pre-authentication connection limits
(after some poking from Pablo Fernandez)
- Exit gracefully if trying to connect to as SSH v1 server
(reported by Rushi Lala)
- Only read /dev/random once at startup when in non-inetd mode
- Allow ctrl-c to close a dbclient password prompt (may
still have to press enter on some platforms)
- Merged in uClinux patch for inetd mode
- Updated to scp from OpenSSH 4.3p2 - fixes a security issue
where use of system() could cause users to execute arbitrary
code through malformed filenames, ref CVE-2006-0225
0.47 - Thurs Dec 8 2005
- SECURITY: fix for buffer allocation error in server code, could potentially
allow authenticated users to gain elevated privileges. All multi-user systems
running the server should upgrade (or apply the patch available on the
Dropbear webpage).
- Fix channel handling code so that redirecting to /dev/null doesn't use
100% CPU.
- Turn on zlib compression for dbclient.
- Set "low delay" TOS bit, can significantly improve interactivity
over some links.
- Added client keyboard-interactive mode support, allows operation with
newer OpenSSH servers in default config.
- Log when pubkey auth fails because of bad ~/.ssh/authorized_keys permissions
- Improve logging of assertions
- Added aes-256 cipher and sha1-96 hmac.
- Fix twofish so that it actually works.
- Improve PAM prompt comparison.
- Added -g (dbclient) and -a (dropbear server) options to allow
connections to listening forwarded ports from remote machines.
- Various other minor fixes
- Compile fixes for glibc 2.1 (ss_family vs __ss_family) and NetBSD
(netinet/in_systm.h needs to be included).
0.46 - Sat July 9 2005
- Fix long-standing bug which caused connections to be closed if an ssh-agent
socket was no longer available
- Print a warning if we seem to be blocking on /dev/random
(suggested by Paul Fox)
- Fixed a memory leak in DSS code (thanks to Boris Berezovsky for the patch)
- dbclient -L no longer segfaults, allocate correct buffer size (thanks
to David Cook for reporting it, and Christopher Faylor for independently
sending in a patch)
- Added RSA blinding to signing code (suggested by Dan Kaminsky)
- Rearranged bignum reading/random generation code
- Reset the non-blocking status on stderr and stdout as well as stdin,
fixes a problem where the shell running dbclient will exit (thanks to
Brent Roman for reporting it)
- Fix so that all file descriptors are closed so the child shell doesn't
inherit descriptors (thanks to Linden May for the patch)
- Change signkey.c to avoid gcc 4 generating incorrect code
- After both sides of a file descriptor have been shutdown(), close()
it to avoid leaking descriptors (thanks to Ari Hyttinen for a patch)
- Update to LibTomCrypt 1.05 and LibTomMath 0.35
0.45 - Mon March 7 2005
- Makefile no longer appends 'static' to statically linked binaries
- Add optional SSH_ASKPASS support to the client
- Respect HOST_LOOKUP option
- Fix accidentally removed "return;" statement which was removed in 0.44
(causing clients which sent an empty terminal-modes string to fail to
connect - including pssh, ssh.com, danger hiptop). (patches
independently from Paul Fox, David Horwitt and Sven-Ola Tuecke)
- Read "y/n" response for fingerprints from /dev/tty directly so that dbclient
will work with scp.
0.44 - Mon Jan 3 2005
- SECURITY: Fix for PAM auth so that usernames are logged and conversation
function responses are allocated correctly - all 0.44test4 users with PAM
compiled in (not default) are advised to upgrade.
- Fix calls to getnameinfo() for compatibility with Solaris
- Pristine compilation works (run 'configure' from a fresh dir and make it
there)
- Fixes for compiling with most options disabled.
- Upgraded to LibTomCrypt 0.99 and LibTomMath 0.32
- Make sure that zeroing out of values in LTM and LTC won't get optimised away
- Removed unused functions from loginrec.c
- /dev/random is now the default entropy source rather than /dev/urandom
- Logging of IPs in auth success/failure messages for improved greppability
- Fix dbclient so that "scp -i keyfile" works. (It can handle "-ikeyfile
properly)
- Avoid a race in server shell-handling code which prevents the exit-code
from being returned to the client in some circumstances.
- Makefile modified so that install target works correctly (doesn't try
to install "all" binary) - patch from Juergen Daubert
- Various minor fixes and compile warnings.
0.44test4 - Tue Sept 14 2004 21:15:54 +0800
- Fix inetd mode so it actually loads the hostkeys (oops)
- Changed DROPBEAR_DEFPORT properly everywhere
- Fix a small memory leak in the auth code
- WCOREDUMP is only used on systems which support it (ie not cygwin or AIX)
- Check (and fail for) cases when we can't negotiate algorithms with the
remote side successfully (rather than bombing out ungracefully)
- Handle authorized_keys files without a terminating newline
- Fiddle the channel receive window size for possibly better performance
- Added in the PAM authentication code (finally! thanks to Martin Carlsson)
0.44test3 - Fri Aug 27 22:20:54 +0800
- Fixed a bunch of warnings.
- scp works correctly when passed a username (fix for the dbclient program
itself as well, "-lmatt" works as well as "-l matt").
- Remove unrequired debian files
- Exit with the remote process's return code for dbclient
- Display stderr messages from the server in the client
- Add circular buffering to the channel code. This should dramatically reduce
the amount of backtraffic sent in response to traffic incoming to the
Dropbear end - improves high-latency performance (ie dialup).
- Various other related channel-handling fixups.
- Allow leading lines in the banner when connecting to servers
- Fixed printing out errors onto the network socket with stderr (for inetd
mode when using xinetd)
- Remove obselete documentation
- Fix a null-pointer exception when trying to free non-existant listeners
at cleanup.
- DEBUG_TRACE now only works if you add "-v" to the program commandline
- Don't leave stdin non-blocking on exit - this caused the parent shell
of dbclient to close when dbclient exited, for some shells in BusyBox
- Server connections no longer timeout after 5 minutes
- Fixed stupid DSS hostkey typo (server couldn't load host keys)
0.44test2 - Tues Aug 17 2004 17:43:54 +0800
- Fix up dropbearmulti targets in the Makefile - symlinks are now created
- Compile fake-rfc2553 even with dropbearconvert/dropbearkey - this
allows them to work on platforms without a native getaddrinfo()
- Create ~/.ssh/known_hosts properly if it doesn't exist
- Fix basename() function prototype
- Backport some local changes (more #ifdefs for termcodes.c, a fix for missing
defines on AIX).
- Let dbclient be run as "ssh"
- Initialise mp_ints by default
0.44test1 - Sun Aug 16 2005 17:43:54 +0800
- TESTING RELEASE - this is the first public release of the client codebase,
so there are sure to be bugs to be found. In addition, if you're just using
the server portion, the final binary size probably will increase - I'll
be trying to get it back down in future releases.
- Dropbear client added - lots of changes to the server code as well to
generalise things
- IPv6 support added for client, server, and forwarding
- New makefile with more generic support for multiple-program binaries
0.43 - Fri Jul 16 2004 17:44:54 +0800
- SECURITY: Don't try to free() uninitialised variables in DSS verification
code. Thanks to Arne Bernin for pointing out this bug. This is possibly
exploitable, all users with DSS and pubkey-auth compiled in are advised to
upgrade.
- Clean up agent forwarding socket files correctly, patch from Gerrit Pape.
- Don't go into an infinite loop when portforwarding to servers which don't
send any initial data/banner. Patch from Nikola Vladov
- Fix for network vs. host byte order in logging remote TCP ports, also
from Gerrit Pape.
- Initialise many pointers to NULL, for general safety. Also checked cleanup
code for mp_ints (related to security issues above).
0.42 - Wed Jun 16 2004 12:44:54 +0800
- Updated to Gerrit Pape's official Debian subdirectory
- Fixed bad check when opening /dev/urandom - thanks to Danny Sung.
- Added -i inetd mode flag, and associated options in options.h . Dropbear
can be compiled with either normal mode, inetd, or both modes. Thanks
to Gerrit Pape for basic patch and motivation.
- Use <dirent.h> rather than <sys/dir.h> for POSIX compliance. Thanks to Bill
Sommerfield.
- Fixed a TCP forwarding (client-local, -L style) bug which caused the whole
session to close if the TCP connection failed. Thanks to Andrew Braund for
reporting it and helping track it down.
- Re-enable sigpipe for child processes. Thanks to Gerrit Pape for some
suggestions, and BSD manpages for a clearer explanation of the behaviour.
- Added manpages, thanks to Gerrit Pape.
- Changed license text for LibTomCrypt and LibTomMath.
- Added strip-static target
- Fixed a bug in agent-forwarding cleanup handler - would segfault
(dereferencing a null pointer) if agent forwarding had failed.
- Fix behaviour of authorized_keys parsing, so larger (>1024 bit) DSA keys will
work. Thanks to Dr. Markus Waldeck for the report.
- Fixed local port forwarding code so that the "-j" option will make forwarding
attempts fail more gracefully.
- Allow repeated requests in a single session if previous ones fail - this fixes PuTTY and some other SCP clients, which try SFTP, then fall-back to SCP if it
isn't available. Thanks to Stirling Westrup for the report.
- Updated to LibTomCrypt 0.96 and LibTomMath 0.30. The AES code now uses
smaller non-precomputed tables if DROPBEAR_SMALL_CODE is defined in
options.h, leading to a significant reduction in the binary size.
0.41 - Mon Jan 19 2004 22:40:19 +0800
- Fix in configure so that cross-compiling works, thanks to numerous people for
reporting and testing
- Terminal mode parsing now handles empty terminal mode strings (sent by
Windows ssh.com clients), thanks to Ricardo Derbes for the report
- Handling is improved for users with no shell specified in /etc/passwd,
thanks again to Ricardo Derbes
- Fix for compiling with --disable-syslog, thanks to gordonfh
- Various minor fixes allow scp to work with irix, thanks to Paul Marinceu for
fixing it up
- Use <stropts.h> not <sys/stropts.h>, since the former seems more common
0.40 - Tue Jan 13 2004 21:05:19 +0800
- Remote TCP forwarding (-R) style implemented
- Local and remote TCP forwarding can each be disabled at runtime (-k and -j
switches)

people for reporting and testing fixes, including (in random order) Cristian
Ionescu-Idbohrn, James Ewing, Steve Dover, Thomas Lundquist and Frederic
Lavernhe
- Improved portability for IRIX, thanks to Paul Marinceu
- AIX and HPUX portability fixes, thanks to Darren Tucker for patches
- prngd should now work correctly, thanks to Darren Tucker for the patch
- scp compilation on systems without strlcpy() is fixed, thanks to Peter
Jannesen and David Muse for reporting it (independently and simultaneously :)
- Merged in new LibTomCrypt 0.92 and LibTomMath 0.28
0.39 - Tue Dec 16 2003 15:19:19 +0800

(also thanks to Mihnea Stoenescu)
- Various makefile improvements for cross-compiling, thanks to Friedrich
Lobenstock and Mihnea Stoenescu

code (thanks to Fr<46>d<EFBFBD>ric Lavernhe for the report and debugging, and Bernard
Blackham for his suggestion on what to look at)
- Fixed up support for first_kex_packet_follows, required to talk to ssh.com
clients. Thanks to Marian Stagarescu for the bug report.
- Avoid using MAXPATHLEN, pointer from Ian Morris
- Improved input sanity checking
0.38 - Sat Oct 11 2003 16:28:13 +0800
- Default hostkey path changed to /etc/dropbear/dropbear_{rsa,dss}_host_key
rather than /etc/dropbear_{rsa,dss}_host_key

binaries or small binaries
- Allow for commandline definition of some options.h settings
(without warnings)
- Be more careful handling EINTR
- More fixes for channel closing
- Added multi-binary support
- Improved logging of IPs, now get logged in all cases
- Don't chew cpu when waiting for version identification string, also
make sure that we kick off people if they don't auth within 5 minutes.
- Various small fixes, warnings etc
- Display MOTD if requested - suggested by
Trent Lloyd <lathiat at sixlabs.org> and
Zach White <zwhite at darkstar.frop.org>
- sftp support works (relies on OpenSSH sftp binary or similar)

Thanks to Shig for them.
- Improved the closing messages, so a clean exit is "Exited normally"
- Added some more robust integer/size checking in buffer.c as a backstop for
integer overflows
- X11 forwarding fixed for OSX, path for xauth changed to /usr/X11R6/bin/xauth
- Channel code handles closing more nicely, doesn't sit waiting for an extra
keystroke on BSD/OSX platforms, and data is flushed fully before closing
child processes (thanks to
Cristian Ionescu-Idbohrn <cristian.ionescu-idbohrn at axis.com> for
pointing that out).
- Changed "DISABLE_TCPFWD" to "ENABLE_TCPFWD" (and for x11/auth) so
"disable DISABLE_TCPWD" isn't so confusing.
- Fix authorized_keys handling (don't crash on too-long keys, and
use fgetc not getc to avoid strange macro-related issues), thanks to
Cristian Ionescu-Idbohrn <cristian.ionescu-idbohrn at axis.com>
and Steve Rodgers <hwstar at cox.net> for reporting and testing.
- Fixes to the README with regard to uClibc systems, thanks to
Cristian Ionescu-Idbohrn <cristian.ionescu-idbohrn at axis.com>,
as well as general improvements to documentation (split README/INSTALL)
- Fixed up some compilation problems with dropbearconvert/dropbearkey if
DSS or RSA were disabled, reported by Patrik Karlsson <patrik at cqure.net>
- Fix double-free bug for hostkeys, reported by

- Fix up missing \ns from dropbearconvert help message,
thanks to Mordy Ovits <movits at bloomberg.com> for the patch
0.36 - Tue August 19 2003 12:16:23 +0800
- Fix uninitialised temporary variable in DSS signing code

0.34 - Fri August 15 2003 15:10:00 +0800
- Made syslog optional, both at compile time and as a compile option
(suggested by Laurent Bercot <ska at skarnet.org>)
- Fixup for bad base64 parsing in authorized_keys
(noticed by Davyd Madeley <davyd at zdlcomputing.com>)
- Added initial tcp forwarding code, only -L (local) at this stage
- Improved "make install" with DESTDIR and changing ownership seperately,
