========================================================================== Ubuntu Security Notice USN-2315-1 August 14, 2014

serf vulnerability

A security issue affects these releases of Ubuntu and its derivatives:

  • Ubuntu 14.04 LTS
  • Ubuntu 12.04 LTS

Summary:

Fraudulent security certificates could allow sensitive information to be exposed when accessing the Internet.

Software Description: - serf: high-performance asynchronous HTTP client library

Details:

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.

Update instructions:

The problem can be corrected by updating your system to the following package versions:

Ubuntu 14.04 LTS: libserf-1-1 1.3.3-1ubuntu0.1

Ubuntu 12.04 LTS: libserf1 1.0.0-2ubuntu0.1

In general, a standard system update will make all the necessary changes.
