Ubuntu 14.04 LTS : serf vulnerability (USN-2315-1)

medium Nessus Plugin ID 77218

Synopsis

The remote Ubuntu host is missing a security update.

Description

Ben Reser discovered that serf did not correctly handle SSL certificates with NUL bytes in the CommonName or SubjectAltNames fields. A remote attacker could exploit this to perform a man in the middle attack to view sensitive information or alter encrypted communications.

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 libserf-1-1 and / or libserf-dev packages.
