medium Nessus Plugin ID 38966

Synopsis

The remote FreeBSD host is missing one or more security-related updates.

Description

Secunia reports :

Some vulnerabilities have been reported in OpenSSL, which can be exploited by malicious people to cause a DoS.

The library does not limit the number of buffered DTLS records with a future epoch. This can be exploited to exhaust all available memory via specially crafted DTLS packets.

An error when processing DTLS messages can be exploited to exhaust all available memory by sending a large number of out of sequence handshake messages.

Solution

Update the affected packages.
