RedHat: PyXML
Summary
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.
