Ubuntu Security Notice USN-1375-1
February 27, 2012

python-httplib2 vulnerability

A security issue affects these releases of Ubuntu and its derivatives:

• Ubuntu 11.10
• Ubuntu 11.04
• Ubuntu 10.10
• Ubuntu 10.04 LTS

Summary:

httplib2 could be made to expose sensitive information over the network.

Software Description:

• python-httplib2: comprehensive HTTP client library written for Python

Details:

The httplib2 Python library earlier than version 0.7.0 did not perform any
server certificate validation when using HTTPS connections. If a remote
attacker were able to perform a man-in-the-middle attack, this flaw could
be exploited 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 11.10:
python-httplib2 0.7.2-1ubuntu2~0.11.10.1
python3-httplib2 0.7.2-1ubuntu2~0.11.10.1

Ubuntu 11.04:
python-httplib2 0.7.2-1ubuntu2~0.11.04.1
python3-httplib2 0.7.2-1ubuntu2~0.11.04.1

Ubuntu 10.10:
python-httplib2 0.7.2-1ubuntu2~0.10.10.1
python3-httplib2 0.7.2-1ubuntu2~0.10.10.1

Ubuntu 10.04 LTS:
python-httplib2 0.7.2-1ubuntu2~0.10.04.1

In general, a standard system update will make all the necessary changes.

This update uses a new upstream release, which includes additional bug
fixes.
