===================================================================== Red Hat Security Advisory
Synopsis: Moderate: rsyslog security update Advisory ID: RHSA-2011:1247-01 Product: Red Hat Enterprise Linux Advisory URL: https://rhn.redhat.com/errata/RHSA-2011-1247.html Issue date: 2011-09-01 CVE Names: CVE-2011-3200 =====================================================================
1. Summary:
Updated rsyslog packages that fix one security issue are now available for Red Hat Enterprise Linux 6.
The Red Hat Security Response Team has rated this update as having moderate security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section.
2. Relevant releases/architectures:
Red Hat Enterprise Linux Desktop (v. 6) - i386, x86_64 Red Hat Enterprise Linux Desktop Optional (v. 6) - i386, x86_64 Red Hat Enterprise Linux HPC Node (v. 6) - x86_64 Red Hat Enterprise Linux HPC Node Optional (v. 6) - x86_64 Red Hat Enterprise Linux Server (v. 6) - i386, ppc64, s390x, x86_64 Red Hat Enterprise Linux Workstation (v. 6) - i386, x86_64
3. Description:
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.
4. Solution:
Before applying this update, make sure all previously-released errata relevant to your system have been applied.
This update is available via the Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at https://access.redhat.com/kb/docs/DOC-11259
5. Bugs fixed (http://bugzilla.redhat.com/):
727644 - CVE-2011-3200 rsyslog: parseLegacySyslogMsg off-by-two buffer overflow
