USN-2315-1: serf vulnerability
14 August 2014
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 14.04 LTS
- Ubuntu 12.04 LTS
Fraudulent security certificates could allow sensitive information to be exposed when accessing the Internet.
- serf - high-performance asynchronous HTTP client library
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.
The problem can be corrected by updating your system to the following package versions:
To update your system, please follow these instructions: https://wiki.ubuntu.com/Security/Upgrades.
In general, a standard system update will make all the necessary changes.
