Debian Security Advisory

DSA-1935-1 gnutls13 gnutls26 -- several vulnerabilities

Date Reported:

17 Nov 2009

Affected Packages:

gnutls13, gnutls26

Vulnerable:

Yes

Security database references:

In the Debian bugtracking system: Bug 541439.
In Mitre's CVE dictionary: CVE-2009-2409, CVE-2009-2730.

More information:

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)

For the oldstable distribution (etch), these problems have been fixed in version 1.4.4-3+etch5 for gnutls13.

For the stable distribution (lenny), these problems have been fixed in version 2.4.2-6+lenny2 for gnutls26.

For the testing distribution (squeeze), and the unstable distribution (sid), these problems have been fixed in version 2.8.3-1 for gnutls26.

We recommend that you upgrade your gnutls13/gnutls26 packages.

Fixed in:

Debian GNU/Linux 4.0 (etch)
