Vulnerabilities on Ubuntu ..



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.

  CVE-2013-2037

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
  https://launchpad.net/ubuntu/+source/python-httplib2/0.7.2-1ubuntu2.1
  https://launchpad.net/ubuntu/+source/python-httplib2/0.7.2-1ubuntu2~0.10.04.2
..

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 "

imagemagick vulnerability
==========================================================================

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

- Ubuntu 13.04
- Ubuntu 12.10

Summary:

ImageMagick could be made to crash or run programs as your login if it
opened a specially crafted file.

Software Description:
- imagemagick: Image manipulation programs and library

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
  libmagickcore5                  8:6.7.7.10-5ubuntu2.1

Ubuntu 12.10:
  libmagick++5                    8:6.7.7.10-2ubuntu4.1
  libmagickcore5                  8:6.7.7.10-2ubuntu4.1

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