DESCRIPTION:
A vulnerability has been reported in GnuTLS, which can be exploited
by malicious people to disclose potentially sensitive information.

The vulnerability is caused due to the CBC mode encryption of the
Datagram Transport Layer Security (DTLS) implementation exposing
timing differences, which can be exploited to recover parts of the
plaintext via a timing attack.

The vulnerability is reported in versions prior to 3.0.11.

SOLUTION:
Update to version 3.0.11.

PROVIDED AND/OR DISCOVERED BY:
Nadhem Alfardan and Kenny Paterson.
