new upstream version 5.8.5 which fixes CVE-2011-3200

Note that Tenable Network Security has extracted the preceding description block directly from the Fedora security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

The rsyslog packages provide an enhanced, multi-threaded syslog daemon that supports MySQL, syslog/TCP, RFC 3195, permitted sender lists, filtering on any message part, and fine grained output format control.

A two byte buffer overflow flaw was found in the rsyslog daemon's parseLegacySyslogMsg function. An attacker able to submit log messages to rsyslogd could use this flaw to crash the daemon. (CVE-2011-3200)

All rsyslog users should upgrade to these updated packages, which contain a backported patch to correct this issue. After installing this update, the rsyslog daemon will be restarted automatically.

The remote NewStart CGSL host, running version CORE 5.04 / MAIN 5.04, has rsyslog packages installed that are affected by a vulnerability:

  - Stack-based buffer overflow in the parseLegacySyslogMsg     function in tools/syslogd.c in rsyslogd in rsyslog 4.6.x     before 4.6.8 and 5.2.0 through 5.8.4 might allow remote     attackers to cause a denial of service (application     exit) via a long TAG in a legacy syslog message.
    (CVE-2011-3200)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

The remote Redhat Enterprise Linux 6 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2011:1247 advisory.

  - rsyslog: parseLegacySyslogMsg off-by-two buffer overflow (CVE-2011-3200)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

A vulnerability was discovered and corrected in rsyslog :

Stack-based buffer overflow in the parseLegacySyslogMsg function in tools/syslogd.c in rsyslogd in rsyslog 4.6.x before 4.6.8 and 5.2.0 through 5.8.4 might allow remote attackers to cause a denial of service (application exit) via a long TAG in a legacy syslog message (CVE-2011-3200).

The updated packages have been patched to correct this issue.

It was discovered that rsyslog had an off-by-two error when parsing legacy syslog messages. An attacker could potentially exploit this to cause a denial of service via application crash.
