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.

Package Information:
https://launchpad.net/ubuntu/+source/python-httplib2/0.7.7-1ubuntu0.1
https://launchpad.net/ubuntu/+source/python-httplib2/0.7.4-2ubuntu0.1

..
To make sure your system is not vulnerable go on to Linux terminal and type " locate python-httplib2" then navigate into the file with command cd in my case was " cd /usr/share/sbin/doc/python-httplib2" Read the copyright documents ... with "less copyright" command and then ...
Upgrade it by running "sudo apt-get install python-httplib2 "

Details:
It was discovered that ImageMagick incorrectly handled decoding GIF image
comments. If a user or automated system using ImageMagick were tricked into
opening a specially crafted GIF image, an attacker could exploit this to
cause a denial of service or possibly execute code with the privileges of
the user invoking the program.
Update instructions:
The problem can be corrected by updating your system to the following
package versions:
Ubuntu 13.04:
libmagick++5 8:6.7.7.10-5ubuntu2.1
