The 4Suite package contains XML-related tools and libraries for Python, including 4DOM, 4XSLT, 4XPath, 4RDF, and 4XPointer. A buffer over-read flaw was found in the way 4Suite"s XML parser handles malformed UTF-8 sequences when processing XML files. A specially-crafted XML file could cause applications using the 4Suite library to crash while parsing the file. Note: In Red Hat Enterprise Linux 3, this flaw only affects a non-default configuration of the 4Suite package: configurations where the beta version of the cDomlette module is enabled. All 4Suite users should upgrade to this updated package, which contains a backported patch to correct this issue. After installing the updated package, applications using the 4Suite XML-related tools and libraries must be restarted for the update to take effect.
