FreeBSD : OpenSSL -- multiple vulnerabilities (5ac53801-ec2e-11e3-9cf3-3c970e169bc2)

High Nessus Plugin ID 74342

Synopsis

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

Description

The OpenSSL Project reports :

An attacker using a carefully crafted handshake can force the use of weak keying material in OpenSSL SSL/TLS clients and servers. This can be exploited by a Man-in-the-middle (MITM) attack where the attacker can decrypt and modify traffic from the attacked client and server.
[CVE-2014-0224]

By sending an invalid DTLS handshake to an OpenSSL DTLS client the code can be made to recurse eventually crashing in a DoS attack.
[CVE-2014-0221]

A buffer overrun attack can be triggered by sending invalid DTLS fragments to an OpenSSL DTLS client or server. This is potentially exploitable to run arbitrary code on a vulnerable client or server.
[CVE-2014-0195]

OpenSSL TLS clients enabling anonymous ECDH ciphersuites are subject to a denial of service attack. [CVE-2014-3470]

Solution

Update the affected packages.
