Ubuntu Security Notice USN-1338-1
23rd January, 2012
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 message.
- 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.
The problem can be corrected by updating your system to the following package version:
To update your system, please follow these instructions: https://wiki.ubuntu.com/Security/Upgrades.
In general, a standard system update will make all the necessary changes.
