Red Hat: Updated rsyslog packages fix one security issue

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. Updated packages are available from ftp.redhat.com.
