Type:	Security Advisory
Severity:	Moderate
Issued on:	2007-12-10
Last updated on:	2007-12-10
Affected Products:	Red Hat Enterprise Linux AS (v. 2.1) Red Hat Enterprise Linux ES (v. 2.1) Red Hat Enterprise Linux WS (v. 2.1) Red Hat Linux Advanced Workstation 2.1 for the Itanium Processor
CVEs (cve.mitre.org):	CVE-2006-7228 CVE-2007-2052

Details

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 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, 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.

Solution

Before applying this update, make sure that all previously-released
