Synopsis

The remote Debian host is missing a security-related update.

Description

A flaw was reported in the DTLS protocol implementation in GnuTLS, a library implementing the TLS and SSL protocols. The DTLS client would not contribute any randomness to the DTLS negotiation, breaking the security guarantees of the DTLS protocol.
