    Package        : gnutls26
    CVE ID         : CVE-2015-8313
    
    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.
