Please Install the Updated Packages.

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.
