Ubuntu Security Notice USN-1338-1
January 23, 2012

rsyslog vulnerability

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 11.04


Rsyslog could be made to crash if it processed a specially crafted log

Software Description:
- rsyslog: Enhanced syslogd


Peter Eisentraut discovered that Rsyslog would not properly perform input
validation when configured to use imfile. If an attacker were able to
craft messages in a file that Rsyslog monitored, an attacker could cause a
denial of service. The imfile module is disabled by default in Ubuntu.

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 11.04:
  rsyslog                         4.6.4-2ubuntu4.2

In general, a standard system update will make all the necessary changes.
