## Description

The (1) TLS and (2) DTLS implementations in OpenSSL 1.0.1 before 1.0.1g do
not properly handle Heartbeat Extension packets, which allows remote
attackers to obtain sensitive information from process memory via crafted
packets that trigger a buffer over-read, as demonstrated by reading private
keys, related to d1\_both.c and t1\_lib.c, aka the Heartbleed bug.
