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

medium Nessus Plugin ID 43627

Language:

Synopsis

The remote Red Hat host is missing a security update for PyXML.

Description

The remote Redhat Enterprise Linux 4 / 5 host has a package installed that is affected by a vulnerability as referenced in the RHSA-2010:0002 advisory.

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.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the RHEL PyXML package based on the guidance in RHSA-2010:0002.
