Detail

Problem Description:

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.

2. Relevant releases/architectures:

Red Hat Enterprise Linux AS (Advanced Server) version 2.1 - i386, ia64 Red Hat Linux Advanced Workstation 2.1 - ia64 Red Hat Enterprise Linux ES version 2.1 - i386 Red Hat Enterprise Linux WS version 2.1 - i386

3. Problem description:

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.

4. Solution:

Before applying this update, make sure that all previously-released errata relevant to your system have been applied.

This update is available via Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at http://kbase.redhat.com/faq/FAQ_58_10188

5. Bug IDs fixed (http://bugzilla.redhat.com/):

235093 - CVE-2007-2052 Off-by-one in python's locale.strxfrm() 383371 - CVE-2006-7228 pcre integer overflow

Title:	Integer overflow in Perl-Compatible Regular Expression (PCRE) library before 6.7 might allow context-dependent attackers to execute arbitrary code via a regular expression that involves large (1) min, (2) max, or (3) duplength values that cause an incorrect length calculation and trigger a buffer overflow, a different vulnerability than CVE-2006-7227. NOTE: this issue was originally subsumed by CVE-2006-7224, but that CVE has been REJECTED and split.
