OpenSSH 5.2 has just been released. It will be available from the

mirrors listed at http://www.openssh.com/ shortly.
OpenSSH is a 100% complete SSH protocol version 1.3, 1.5 and 2.0

implementation and includes sftp client and server support.
We have also recently completed another Internet SSH usage scan, the

results of which may be found at http://www.openssh.com/usage.html
Once again, we would like to thank the OpenSSH community for their

continued support of the project, especially those who contributed

code or patches, reported bugs, tested snapshots or donated to the

project. More information on donations may be found at:

http://www.openssh.com/donations.html
The focus of this release has been on bugfixes as the previous

openssh-5.1 release introduced many new features and made some

invasive changes.
Changes since OpenSSH 5.1

=========================
Security:
 * This release changes the default cipher order to prefer the AES CTR

   modes and the revised "arcfour256" mode to CBC mode ciphers that are

   susceptible to CPNI-957037 "Plaintext Recovery Attack Against SSH".
 * This release also adds countermeasures to mitigate CPNI-957037-style

   attacks against the SSH protocol's use of CBC-mode ciphers. Upon

   detection of an invalid packet length or Message Authentication

   Code, ssh/sshd will continue reading up to the maximum supported

   packet length rather than immediately terminating the connection.

   This eliminates most of the known differences in behaviour that

   leaked information about the plaintext of injected data which formed

   the basis of this attack. We believe that these attacks are rendered

   infeasible by these changes.
New features:
 * Added a -y option to ssh(1) to force logging to syslog rather than

   stderr, which is useful when running daemonised (ssh -f)
 * The sshd_config(5) ForceCommand directive now accepts commandline

   arguments for the internal-sftp server.
 * The ssh(1) ~C escape commandline now support runtime creation of

   dynamic (-D) port forwards.
 * Support the SOCKS4A protocol in ssh(1) dynamic (-D) forwards.

   (bz#1482)
 * Support remote port forwarding with a listen port of '0'. This

   informs the server that it should dynamically allocate a listen

   port and report it back to the client. (bz#1003)
 * sshd(8) now supports setting PermitEmptyPasswords and

   AllowAgentForwarding in Match blocks
Bug and documentation fixes
 * Repair a ssh(1) crash introduced in openssh-5.1 when the client is

   sent a zero-length banner (bz#1496)
 * Due to interoperability problems with certain

   broken SSH implementations, the eow@openssh.com and

   no-more-sessions@openssh.com protocol extensions are now only sent

   to peers that identify themselves as OpenSSH.
 * Make ssh(1) send the correct channel number for

   SSH2_MSG_CHANNEL_SUCCESS and SSH2_MSG_CHANNEL_FAILURE messages to

   avoid triggering 'Non-public channel' error messages on sshd(8) in

   openssh-5.1.
 * Avoid printing 'Non-public channel' warnings in sshd(8), since the

   ssh(1) has sent incorrect channel numbers since ~2004 (this reverts

   a behaviour introduced in openssh-5.1).
 * Avoid double-free in ssh(1) ~C escape -L handler (bz#1539)
 * Correct fail-on-error behaviour in sftp(1) batchmode for remote

   stat operations. (bz#1541)
 * Disable nonfunctional ssh(1) ~C escape handler in multiplex slave

   connections. (bz#1543)
 * Avoid hang in ssh(1) when attempting to connect to a server that

   has MaxSessions=0 set.
 * Multiple fixes to sshd(8) configuration test (-T) mode
 * Several core and portable OpenSSH bugs fixed: 1380, 1412, 1418,

   1419, 1421, 1490, 1491, 1492, 1514, 1515, 1518, 1520, 1538, 1540
 * Many manual page improvements.
