The utf-16 decoder in Python 3.1 through 3.3 does not update the aligned_end variable after calling the unicode_decode_call_errorhandler function, which allows remote attackers to obtain sensitive information (process memory) or cause a denial of service (memory corruption and crash) via unspecified vectors.

python3 was fixed for :

  - Fix bnc#758993 - CVE-2012-2135: python3 utf-16 decoder     unicode_decode_call_errorhandler aligned_end is not     updated

It was discovered that Python would prepend an empty string to sys.path under certain circumstances. A local attacker with write access to the current working directory could exploit this to execute arbitrary code. This issue only affected Ubuntu 10.04 LTS.
(CVE-2008-5983)

It was discovered that the audioop module did not correctly perform input validation. If a user or automated system were tricked into opening a crafted audio file, an attacker could cause a denial of service via application crash. These issues only affected Ubuntu 10.04 LTS. (CVE-2010-1634, CVE-2010-2089)

It was discovered that Python distutils contained a race condition when creating the ~/.pypirc file. A local attacker could exploit this to obtain sensitive information. (CVE-2011-4944)

It was discovered that SimpleXMLRPCServer did not properly validate its input when handling HTTP POST requests. A remote attacker could exploit this to cause a denial of service via excessive CPU utilization. (CVE-2012-0845)

It was discovered that Python was susceptible to hash algorithm attacks. An attacker could cause a denial of service under certian circumstances. This update adds the '-R' command line option and honors setting the PYTHONHASHSEED environment variable to 'random' to salt str and datetime objects with an unpredictable value.
(CVE-2012-1150)

Serhiy Storchaka discovered that the UTF16 decoder in Python did not properly reset internal variables after error handling. An attacker could exploit this to cause a denial of service via memory corruption.
(CVE-2012-2135).

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
