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.
