Description Silvio Cesare 2010-11-12 03:41:33 UTC

Description of problem:

libtlen contains an old embedded version of the expat xml parsing library. Code inspection shows this embedded copy is vulnerable to CVE-2009-3720 and possibly other issues.

Version-Release number of selected component (if applicable):

Version: 0
Release: 0.9.20060309.fc12

Additional info:

Ideally, the best solution is to link in the system expat library and not use the embedded copy. This would help prevent these types of security issues from reoccuring.

I have marked this issue as a security issue due to the fact that a CVE was assigned to expat. I have not investigated how this vulnerability would be triggered by libtlen.
