USN-1948-1: httplib2 vulnerability
Ubuntu Security Notice USN-1948-1
9th September, 2013
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
Fraudulent security certificates could allow sensitive information to be exposed when accessing the Internet.
- python-httplib2 - comprehensive HTTP client library written in Python
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.
The problem can be corrected by updating your system to the following package version:
- 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
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.
