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