Issue Overview:

It was discovered that GnuTLS leaked timing information when decrypting TLS/SSL protocol encrypted records when CBC-mode cipher suites were used. A remote attacker could possibly use this flaw to retrieve plain text from the encrypted packets by using a TLS/SSL server as a padding oracle. (CVE-2013-1619)
