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.

Recent assessments:

zeroSteiner at April 13, 2020 8:54pm UTC reported:

A missing boundary check causes versions of OpenSSL 1.0.1 – 1.0.1f to be vulnerable to an out of bounds read as part of an SSL Heartbeat message. This vulnerability can be leveraged without authenticating in many instances to leak sensitive information such as passwords and private keys. Due to the vulnerability being in the OpenSSL library, exploits are implementation specific and may require changes to implement the applicable protocol.

The vulnerability was fixed in this patch.
