USN-1338-1: Rsyslog vulnerability
23 January 2012
Rsyslog could be made to crash if it processed a specially crafted log message.
Releases
Packages
- rsyslog - Enhanced syslogd
Details
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
In general, a standard system update will make all the necessary changes.
