========================================================================== Ubuntu Security Notice USN-1948-1 September 09, 2013
python-httplib2 vulnerability ==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 13.04 - Ubuntu 12.10 - Ubuntu 12.04 LTS - Ubuntu 10.04 LTS
Summary:
Fraudulent security certificates could allow sensitive information to be exposed when accessing the Internet.
Software Description: - python-httplib2: comprehensive HTTP client library written for Python
Details:
It was discovered that httplib2 only validated SSL certificates on the first request to a connection, and didn't report validation failures on subsequent requests. If a remote attacker were able to perform a man-in-the-middle attack, this flaw could possibly be exploited in certain scenarios to alter or compromise confidential information in applications that used the httplib2 library.
Update instructions:
The problem can be corrected by updating your system to the following package versions:
Ubuntu 13.04: python-httplib2 0.7.7-1ubuntu0.1
Ubuntu 12.10: python-httplib2 0.7.4-2ubuntu0.1
Ubuntu 12.04 LTS: python-httplib2 0.7.2-1ubuntu2.1
Ubuntu 10.04 LTS: python-httplib2 0.7.2-1ubuntu2~0.10.04.2
In general, a standard system update will make all the necessary changes.
