Description
It was discovered that GnuTLS did not correctly handle certain errors 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)
A flaw was found in the way GnuTLS handled version 1 X.509 certificates.
An attacker able to obtain a version 1 certificate from a trusted
certificate authority could use this flaw to issue certificates for other
sites that would be accepted by GnuTLS as valid. (CVE-2009-5138)
