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. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2009-3720 to this issue.
This update makes PyXML use the system Expat library rather than its own internal copy; therefore, the RHSA-2009:1625 expat update needs to be included with this PyXML update to resolve the CVE-2009-3720 issue.

networking and security best practices by implementing
firewalls, ACLs, physical security or other appropriate
access restrictions. Though Avaya believes such
restrictions should always be in place; risk to Avaya's

vulnerability may be mitigated by ensuring these
practices are implemented until such time as a product
actions is applied. Further restrictions as deemed
necessary based on the customer's security policies
may be required during this interim period.
