high Nessus Plugin ID 135283

Synopsis

The remote Ubuntu host is missing a security-related patch.

Description

It was discovered that GnuTLS incorrectly handled randomness when performing DTLS negotiation. A remote attacker could possibly use this issue to obtain sensitive information, contrary to expectations.

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
