Red Hat Security Advisory
Synopsis: Moderate: openssh security and bug fix update
Advisory ID: RHSA-2007:0703-02
Advisory URL: https://rhn.redhat.com/errata/RHSA-2007-0703.html
Issue date: 2007-11-15

Product: Red Hat Enterprise Linux
Keywords: GSSAPI krb5 audit pam session DNS memory leak restart sftp
CVE Names: CVE-2006-5052 CVE-2007-3102

1. Summary:
Updated openssh packages that fix two security issues and various bugs are
now available.
This update has been rated as having moderate security impact by the Red
Hat Security Response Team.
2. Relevant releases/architectures:
Red Hat Enterprise Linux AS version 4 - i386, ia64, ppc, s390, s390x, x86_64
Red Hat Enterprise Linux Desktop version 4 - i386, x86_64
Red Hat Enterprise Linux ES version 4 - i386, ia64, x86_64
Red Hat Enterprise Linux WS version 4 - i386, ia64, x86_64
3. Problem description:
OpenSSH is OpenBSD's SSH (Secure SHell) protocol implementation. These
packages include the core files necessary for both the OpenSSH client and
server.
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.
All users of openssh should upgrade to these updated packages, which
contain patches to correct these issues.
