Ubuntu 14.04 LTS : librelp vulnerability (USN-3612-1)

critical Nessus Plugin ID 108710

Language:

Synopsis

The remote Ubuntu host is missing a security update.

Description

Bas van Schaik and Kevin Backhouse discovered that librelp incorrectly handled checking certain x509 certificates. A remote attacker able to connect to rsyslog could possibly use this issue to execute arbitrary code.

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 librelp-dev and / or librelp0 packages.
