Scientific Linux Security Update : openssh on SL4.x i386/x86_64

This script is Copyright (C) 2012 Tenable Network Security, Inc.

Synopsis :

The remote Scientific Linux host is missing one or more security

Description :

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

- 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

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