UBUNTU-CVE-2014-3572

The ssl3getkeyexchange function in s3clnt.c in OpenSSL before 0.9.8zd, 1.0.0 before 1.0.0p, and 1.0.1 before 1.0.1k allows remote SSL servers to conduct ECDHE-to-ECDH downgrade attacks and trigger a loss of forward secrecy by omitting the ServerKeyExchange message...

Vulnerability in OpenSSL - ECDHE silently downgrades to ECDH [Client]

An OpenSSL client will accept a handshake using an ephemeral ECDH ciphersuite using an ECDSA certificate if the server key exchange message is omitted. This effectively removes forward secrecy from the ciphersuite. Found by Karthikeyan Bhargavan of the PROSECCO team at INRIA...

[Beast-Check] SSL/TLS BEAST Vulnerability Check

A small perl script that checks a target server whether it is prone to BEAST vulnerability via target preferred cipher. It assumes no workaround i.e. EMPTY FRAGMENT applied in target server. Some sources said this workaround was disabled by default for compatibility reasons. This may be the reaso...

Authentication flaw

crypto/bn/bnnist.c in OpenSSL before 0.9.8h on 32-bit platforms, as used in stunnel and other products, in certain circumstances involving ECDH or ECDHE cipher suites, uses an incorrect modular reduction algorithm in its implementation of the P-256 and P-384 NIST elliptic curves, which allows...

CVE-2011-4354

OpenSSL vulnerability CVE-2011-4354 affects OpenSSL before 0.9.8h on 32-bit platforms, in the ECDH/ECDHE handshake with P-256 and P-384 curves, due to an incorrect modular reduction algorithm in bn_nist.c. This design flaw allows remote attackers to obtain the TLS server private key after multipl...
