Ubuntu Security Notice USN-2121-1

gnutls26 vulnerability
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 13.10
- Ubuntu 12.10
- Ubuntu 12.04 LTS

Summary:

GnuTLS incorrectly validated certain intermediate certificates.

Software Description:
- gnutls26: GNU TLS library

Details:

Suman Jana discovered that GnuTLS incorrectly handled version 1
intermediate certificates. This resulted in them being considered to be a
valid CA certificate by default, which was contrary to documented
behaviour.

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 13.10:
  libgnutls26                     2.12.23-1ubuntu4.1

Ubuntu 12.10:
  libgnutls26                     2.12.14-5ubuntu4.5

Ubuntu 12.04 LTS:
  libgnutls26                     2.12.14-5ubuntu3.6

In general, a standard system update will make all the necessary changes.
