Mandriva Linux Security Advisory MDVSA-2008:192
http://www.mandriva.com/security/
_______________________________________________________________________

Package : libxml2
Date : September 11, 2008
Affected: 2007.1, 2008.0, 2008.1, Corporate 3.0, Corporate 4.0
_______________________________________________________________________

Problem Description:

A heap-based buffer overflow was found in how libxml2 handled long
XML entity names. If an application linked against libxml2 processed
untrusted malformed XML content, it could cause the application to
crash or possibly execute arbitrary code (CVE-2008-3529).

The updated packages have been patched to prevent this issue.
As well, the patch to fix CVE-2008-3281 has been updated to remove
the hard-coded entity limit that was set to 5M, instead using XML
entity density heuristics. Many thanks to Daniel Veillard of Red Hat
for his hard work in tracking down and dealing with the edge cases
discovered with the initial fix to this issue.
