"Dan Kaminsky and Moxie Marlinspike discovered that gnutls, an
implementation of the TLS/SSL protocol, does not properly handle a
'\0' character in a domain name in the subject's Common Name or
Subject Alternative Name (SAN) field of an X.509 certificate, which
allows man-in-the-middle attackers to spoof arbitrary SSL servers via
a crafted certificate issued by a legitimate Certification Authority.
(CVE-2009-2730 )

In addition, with this update, certificates with MD2 hash signatures
are no longer accepted since they're no longer considered
cryptograhically secure. It only affects the oldstable distribution
(etch).(CVE-2009-2409 )"
