==========================================================================
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.
