(RHSA-2009:1572) Moderate: 4Suite security update

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. (CVE-2009-3720)

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.
