Description Preview
The (1) TLS and (2) DTLS implementations in OpenSSL 1.0.1 before 1.0.1g do not properly handle Heartbeat Extension packets, which can lead to a buffer over-read vulnerability. This vulnerability enables remote attackers to read sensitive information from the memory of the affected system, potentially exposing private keys. The bug is specifically related to the files d1_both.c and t1_lib.c in OpenSSL.
Overview
The Heartbleed bug (CVE-2014-0160) affects OpenSSL versions 1.0.1 before 1.0.1g. It is a critical vulnerability that allows remote attackers to extract sensitive information from the memory of the affected system by sending crafted packets exploiting the Heartbeat Extension.
Remediation
To remediate the Heartbleed vulnerability, it is recommended to upgrade OpenSSL to version 1.0.1g or later, which includes a fix for this issue. Additionally, affected systems should regenerate any potentially compromised private keys and certificates. Organizations should also consider revoking and reissuing certificates as a precautionary measure.
