Detail

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.
