CVE-2012-2135  (opens in a new tab)
CWE-400  (opens in a new tab)

How to fix?

Upgrade python to version 2.7.4, 3.2.4rc1, 3.3.0b2 or higher.

Overview

Affected versions of this package are vulnerable to Denial of Service (DoS). 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.
