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.
Before applying this update, make sure all previously-released errata
