Synopsis:	Moderate: openssh security and bug fix update
Issue date:	2007-11-15
CVE Names:	CVE-2006-5052 CVE-2007-3102

A flaw was found in the way the ssh server wrote account names to the
audit subsystem. An attacker could inject strings containing parts of audit
messages which could possibly mislead or confuse audit log parsing tools.
(CVE-2007-3102)

A flaw was found in the way the OpenSSH server processes GSSAPI
authentication requests. When GSSAPI authentication was enabled in OpenSSH
server, a remote attacker may have been able to determine if a username is
valid. (CVE-2006-5052)

The following bugs were also fixed:

* the ssh daemon did not generate audit messages when an ssh session was
closed.

* GSSAPI authentication sometimes failed on clusters using DNS or
load-balancing.

* the sftp client and server leaked small amounts of memory in some cases.

* the sftp client didn't properly exit and return non-zero status in batch
mode when the destination disk drive was full.

* when restarting the ssh daemon with the initscript, the ssh daemon was
sometimes not restarted successfully because the old running ssh daemon was
not properly killed.

* with challenge/response authentication enabled, the pam sub-process was
not terminated if the user authentication timed out.
