"This update addresses CVE-2011-1944 (heap-based buffer overflow by
adding a new namespace node to an existing nodeset or merging
nodesets). It is described in detail at
http://scarybeastsecurity.blogspot.com/2011/05/libxml-vulnerability-an
d-interesting.html

It also fixes the broken xpath implementation, which was crashing in
the regression test suite on 32-bit architectures and failing some of
the tests on all architectures.

Note that Tenable Network Security has extracted the preceding
description block directly from the Fedora security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues."
