that could occur during the verification of an X.509 certificate,
causing it to incorrectly report a successful verification. An
attacker could use this flaw to create a specially crafted certificate
that could be accepted by GnuTLS as valid for a site chosen by the
attacker. (CVE-2014-0092)

For the update to take effect, all applications linked to the GnuTLS
library must be restarted."
