FreeBSD : OpenSSL -- Client DoS due to large DH parameter (c82ecac5-6e3f-11e8-8777-b499baebfeaf)
High Nessus Plugin ID 110504
SynopsisThe remote FreeBSD host is missing one or more security-related updates.
DescriptionThe OpenSSL project reports :
During key agreement in a TLS handshake using a DH(E) based ciphersuite a malicious server can send a very large prime value to the client. This will cause the client to spend an unreasonably long period of time generating a key for this prime resulting in a hang until the client has finished. This could be exploited in a Denial Of Service attack.
SolutionUpdate the affected packages.
