FreeBSD : OpenSSL -- multiple vulnerabilities (5ac53801-ec2e-11e3-9cf3-3c970e169bc2)
High Nessus Plugin ID 74342
SynopsisThe remote FreeBSD host is missing one or more security-related updates.
DescriptionThe 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.
By sending an invalid DTLS handshake to an OpenSSL DTLS client the code can be made to recurse eventually crashing in a DoS attack.
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.
OpenSSL TLS clients enabling anonymous ECDH ciphersuites are subject to a denial of service attack. [CVE-2014-3470]
