Package        : xmltooling
Vulnerability  : several
Problem type   : remote
Debian-specific: no

Several vulnerabilities have been discovered in the xmltooling packages,
as used by Shibboleth:

Chris Ries discovered that decoding a crafted URL leads to a crash (and
potentially, arbitrary code execution).

Ian Young discovered that embedded NUL characters in certificate names
were not correctly handled, exposing configurations using PKIX trust
validation to impersonation attacks.

Incorrect processing of SAML metadata ignores key usage constraints.
This minor issue also needs a correction in the opensaml2 packages,
which will be provided in an upcoming stable point release (and,
before that, via stable-proposed-updates).

For the stable distribution (lenny), these problems have been fixed in
version 1.0-2+lenny1.

For the unstable distribution (sid), these problems have been fixed in
version 1.2.2-1.

We recommend that you upgrade your xmltooling packages.
