Updated python packages that fix several security issues are now available for Red Hat Enterprise Linux 2.1.
This update has been rated as having moderate security impact by the Red Hat Security Response Team.
Python is an interpreted, interactive, object-oriented programming language.
An integer overflow flaw was discovered in the way Pythonβs 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 Pythonβs locale module. Strings generated by this function were not properly NULL-terminated, which could possibly cause disclosure of data stored in the memory of a Python application using this function.
(CVE-2007-2052)
Users of Python are advised to upgrade to these updated packages, which contain backported patches to resolve these issues.
