Description Huzaifa S. Sidhpurwala 2015-03-03 02:13:43 EST

It was found that gnutls, did not perform date/time check on CA certificates. Applications compiled against gnutls, will continue to assume that a certificate is valid, even though the CA certificate, (which signed this certificate) has expired.

This issue was fixed in gnutls-2.9.10 via the following commit:
https://gitorious.org/gnutls/gnutls/commit/897cbce62c0263a498088ac3e465aa5f05f8719c
