Description

VulnerabilityLookup (CNA)
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.

Analyst Note

CVE-2014-0160 (Heartbleed) is a canonical zero-day: a critical OpenSSL TLS heartbeat implementation flaw exploited in the wild before patches were available in April 2014. Multiple authoritative sources explicitly label it as a zero-day, and contemporaneous reports document widespread exploitation affecting millions of websites and devices immediately upon discovery.
