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...

CVE-2011-4354

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...
