Description Jan Lieskovsky 2010-10-21 10:57:57 UTC 
A security flaw was found in the way libxml traversed XPath axis
of particular Extensible Markup Language (XML) file and tested
namespace / attribute context nodes for their validity. A remote
attacker could provide a specially-crafted XML file, which once
opened with an application linked against libxml would cause that
application to crash (due stack frame overflow and / or with NULL
pointer dereference on some architectures).
