Package        : libxml2
Vulnerability  : invalid memory access
Problem type   : local (remote)
Debian-specific: no
CVE ID         : CVE-2010-4008

Bui Quang Minh discovered that libxml2, a library for parsing and
handling XML data files, does not well process a malformed XPATH,
causing crash and allowing arbitrary code execution.

For the stable distribution (lenny), this problem has been fixed in
version 2.6.32.dfsg-5+lenny2.

For the testing (squeeze) and unstable (sid) distribution, this problem
has been fixed in version 2.7.8.dfsg-1.

We recommend that you upgrade your libxml2 package.
