RHEL 4 / 5 : PyXML (RHSA-2010:0002)

This script is Copyright (C) 2010-2017 Tenable Network Security, Inc.

Synopsis :

The remote Red Hat host is missing a security update.

Description :

An updated PyXML package that fixes one security issue is now
available for Red Hat Enterprise Linux 4 and 5.

This update has been rated as having moderate security impact by the
Red Hat Security Response Team.

PyXML provides XML libraries for Python. The distribution contains a
validating XML parser, an implementation of the SAX and DOM
programming interfaces, and an interface to the Expat parser.

A buffer over-read flaw was found in the way PyXML's Expat parser
handled malformed UTF-8 sequences when processing XML files. A
specially crafted XML file could cause Python applications using
PyXML's Expat parser to crash while parsing the file. (CVE-2009-3720)

This update makes PyXML use the system Expat library rather than its
own internal copy; therefore, users must install the RHSA-2009:1625
expat update together with this PyXML update to resolve the
CVE-2009-3720 issue.

All PyXML users should upgrade to this updated package, which changes
PyXML to use the system Expat library. After installing this update
along with RHSA-2009:1625, applications using the PyXML library must
be restarted for the update to take effect.
