Title: DSA-1935 gnutls13 gnutls26 -- several vulnerabilities
Description: 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 cryptographically secure. It only affects the oldstable distribution (etch).(CVE-2009-2409)
