Synopsis:	Moderate: PyXML security update
Issue date:	2010-01-04
CVE Names:	CVE-2009-3720

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 December 2009 expat
security update, together with this PyXML update to resolve the
CVE-2009-3720 issue.

After installing this update along with the December 2009 expat security
 update, applications using the PyXML library must be restarted for the
update to take effect.
