Gentoo Linux Security Advisory 201312-3 - Multiple vulnerabilities have been found in OpenSSL allowing remote attackers to determine private keys or cause a Denial of Service. Versions less than 1.0.0i are affected.
380511be6e419bf1f679eb548827eea73dd38dc5884aa3ee7bdc7e4fdf03aa74HP Security Bulletin HPSBMU02764 SSRT100827 2 - Potential security vulnerabilities have been identified with HP System Management Homepage (SMH) running on Linux and Windows. The vulnerabilities could be exploited remotely and locally resulting in cross site request forgery (CSRF), Denial of Service (DoS), execution of arbitrary code, and other vulnerabilities. Revision 2 of this advisory.

ef4dc6d5c693e4d1488186aa6471a0d6ae5ab0b725cd9a055f4101f928dcf379Ubuntu Security Notice 1357-1 - It was discovered that the elliptic curve cryptography (ECC) subsystem in OpenSSL, when using the Elliptic Curve Digital Signature Algorithm (ECDSA) for the ECDHE_ECDSA cipher suite, did not properly implement curves over binary fields. This could allow an attacker to determine private keys via a timing attack. This issue only affected Ubuntu 8.04 LTS, Ubuntu 10.04 LTS, Ubuntu 10.10 and Ubuntu 11.04. Adam Langley discovered that the ephemeral Elliptic Curve Diffie-Hellman (ECDH) functionality in OpenSSL did not ensure thread safety while processing handshake messages from clients. This could allow a remote attacker to cause a denial of service via out-of-order messages that violate the TLS protocol. This issue only affected Ubuntu 8.04 LTS, Ubuntu 10.04 LTS, Ubuntu 10.10 and Ubuntu 11.04. Various other issues were also addressed.

The ephemeral ECDH ciphersuite functionality in OpenSSL 0.9.8 through 0.9.8s and 1.0.x before 1.0.0e does not ensure thread safety during processing of handshake messages, which allows remote attackers to cause a denial of service via out-of-order messages that violate the TLS protocol.

After further updates on this incident, it has been determined that all of DigiNotar's signing certificates can no longer be trusted. Debian, like other software distributors and vendors, has decided to distrust all of DigiNotar's CAs. In this update, this is done in the crypto library (a component of the OpenSSL toolkit) by marking such certificates as revoked. Any application that uses said component should now reject certificates signed by DigiNotar. Individual applications may allow users to override the validation failure. However, making exceptions is highly discouraged and should be carefully verified.
