c82ecac5-6e3f-11e8-8777-b499baebfeafOpenSSL -- Client DoS due to large DH parameter

The 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.

CVE-2018-0732
24673ed7-2bf3-11e7-b291-b499baebfeafLibreSSL -- TLS verification vulnerability

Jakub Jirutka reports:

LibreSSL 2.5.1 to 2.5.3 lacks TLS certificate verification if SSL_get_verify_result is relied upon for a later check of a verification result, in a use case where a user-provided verification callback returns 1, as demonstrated by acceptance of invalid certificates by nginx.
