Ubuntu 11.04 : rsyslog vulnerability (USN-1338-1)

low Nessus Plugin ID 57662

Language:

Synopsis

The remote Ubuntu host is missing a security-related patch.

Description

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.

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Update the affected rsyslog package.
