A critical vulnerability exists in TLS and DTLS implementations within OpenSSL versions 1.0.1 prior to 1.0.1g. Exploitation of this issue enables remote attackers to read arbitrary memory locations, potentially exposing sensitive information.
Upgrade to OpenSSL 1.0.1g or later. Re-issue HTTPS certificates and regenerate asymmetric private keys and shared secret keys, as these may have been compromised.
