"A vulnerability has been found and corrected in GnuTLS :

gnutls_cipher.c in libgnutls in GnuTLS before 2.12.17 and 3.x before
3.0.15 does not properly handle data encrypted with a block cipher,
which allows remote attackers to cause a denial of service (heap
memory corruption and application crash) via a crafted record, as
demonstrated by a crafted GenericBlockCipher structure
(CVE-2012-1573).

The updated packages have been patched to correct this issue.

The GnuTLS packages for Mandriva Linux 2011 has been upgraded to the
2.12.8 version due to problems with the test suite while building it,
additionally a new dependency was added on p11-kit for the PKCS #11
support."
