| 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. |
| |

| 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) |

| |
| 0.45 - Mon March 7 2005 |
| |

| |
| - 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 |
| |

| 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 |

| |
| 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 |

| - 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 |

| 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). |
| |

| |
| - 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 |

| from Gerrit Pape. |
| |
| - Initialise many pointers to NULL, for general safety. Also checked cleanup |
| code for mp_ints (related to security issues above). |
| |

| |
| - Updated to Gerrit Pape's official Debian subdirectory |
| |
| - Fixed bad check when opening /dev/urandom - thanks to Danny Sung. |

| 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. |
| |

| |
| - 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 |

| - Use daemon() function if available (or our own copy) rather than separate |
| code (thanks to Frédéric 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. |

| |
| - 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 |

| - Fixed some invalid assertions in the channel code, fixing the server dying |
| when forwarding X11 connections. |
| - Add dropbearconvert to convert to/from OpenSSH host keys and Dropbear keys |
| - RSA keys now keep p and q parameters for compatibility -- old Dropbear keys |
