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.
