    Package        : gnutls26
    Vulnerability  : incorrect certificate verification
    CVE ID         : CVE-2014-0092
    
    Nikos Mavrogiannopoulos of Red Hat discovered an X.509 certificate
    verification issue in GnuTLS, an SSL/TLS library. A certificate
    validation could be reported sucessfully even in cases were an error
    would prevent all verification steps to be performed.
    
    An attacker doing a man-in-the-middle of a TLS connection could use this
    vulnerability to present a carefully crafted certificate that would be
    accepted by GnuTLS as valid even if not signed by one of the trusted
    authorities.
    
    For the oldstable distribution (squeeze), this problem has been fixed in
    version 2.8.6-1+squeeze3.
    
    For the stable distribution (wheezy), this problem has been fixed in
    version 2.12.20-8+deb7u1.
    
    For the testing distribution (jessie), this problem has been fixed in
    version 2.12.23-13.
    
    For the unstable distribution (sid), this problem has been fixed in
    version 2.12.23-13.
    
    We recommend that you upgrade your gnutls26 packages.
