CentOS Errata and Security Advisory CESA-2007:1076
Python is an interpreted, interactive, object-oriented programming language.
An integer overflow flaw was discovered in the way Python's pcre module handled certain regular expressions. If a Python application used the pcre module to compile and execute untrusted regular expressions, it may be possible to cause the application to crash, or allow arbitrary code execution with the privileges of the Python interpreter. (CVE-2006-7228)
A flaw was discovered in the strxfrm() function of Python's locale module. Strings generated by this function were not properly NULL-terminated. This may possibly cause disclosure of data stored in the memory of a Python application using this function. (CVE-2007-2052)
Multiple integer overflow flaws were discovered in Python's imageop module. If an application written in Python used the imageop module to process untrusted images, it could cause the application to crash, enter an infinite loop, or possibly execute arbitrary code with the privileges of the Python interpreter. (CVE-2007-4965)
Users of Python are advised to upgrade to these updated packages, which contain backported patches to resolve these issues.
