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

medium Nessus Plugin ID 77218

Language:

Synopsis

The remote Ubuntu host is missing a security update.

Description

The remote Ubuntu 14.04 LTS host has packages installed that are affected by a vulnerability as referenced in the USN-2315-1 advisory.

 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 machine-in-the-middle attack to view sensitive information or alter encrypted communications.

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the affected libserf-1-1 and / or libserf-dev packages.
