Synopsis

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

Description

OpenSSL Security Advisory :

A memory leak can occur in the dtls1_buffer_record function under certain conditions.

The memory leak could be exploited by an attacker in a Denial of Service attack through memory exhaustion.
