libxml - buffer overflow

“infamous41md” discovered several buffer overflows in libxml and
libxml2, the XML C parser and toolkits for GNOME. Missing boundary
checks could cause several buffers to be overflown, which may cause
the client to execute arbitrary code.

The following vulnerability matrix lists corrected versions of these
libraries:

For the stable distribution (woody) these problems have been fixed in
version 1.8.17-2woody2 of libxml and in version 2.4.19-4woody2 of
libxml2.

For the unstable distribution (sid) these problems have been fixed in
version 1.8.17-9 of libxml and in version 2.6.11-5 of libxml2.

These problems have also been fixed in version 2.6.15-1 of libxml2 in
the experimental distribution.

We recommend that you upgrade your libxml packages.
