Detail

It was discovered that GnuTLS, a library implementing the TLS and SSL protocols, incorrectly validates the first byte of padding in CBC modes. A remote attacker can possibly take advantage of this flaw to perform a padding oracle attack.

For the oldstable distribution (wheezy), this problem has been fixed in version 2.12.20-8+deb7u4.

We recommend that you upgrade your gnutls26 packages.
