Description Sam James archtester

"When a single trust list object is shared among multiple threads, calls to gnutls_x509_trust_list_verify_crt2() was able to corrupt temporary memory where internal copy of an issuer certificate is stored. The code path is only taken when a PKCS#11 based trust store is enabled and the issuer certificate is already stored as trusted. The issue was reported in the issue tracker as #1277.
Recommendation: To address the issue found upgrade to GnuTLS 3.7.3 or later versions."
