Microsoft windows Schannel weak Diffie-Hellman ephemeral key length sensitive information disclosure vulnerability

Microsoft Windows is a popular operating system. A security vulnerability exists in Microsoft Windows Schannel when a 512-bit weak Diffie-Hellman ephemeral key length is used in an encrypted TLS session, which allows remote attackers to decrypt the weak key and obtain sensitive information by...

openssl: only allow ephemeral RSA keys in export ciphersuites (FREAK)

It was discovered that OpenSSL would accept ephemeral RSA keys when using non-export RSA cipher suites. A malicious server could make a TLS/SSL client using OpenSSL use a weaker key exchange method...

openssl: ECDH downgrade bug fix

It was discovered that OpenSSL would perform an ECDH key exchange with a non-ephemeral key even when the ephemeral ECDH cipher suite was selected. A malicious server could make a TLS/SSL client using OpenSSL use a weaker key exchange method than the one requested by the user...

Updated openssl packages fix security vulnerabilities

A carefully crafted DTLS message can cause a segmentation fault in OpenSSL due to a NULL pointer dereference. This could lead to a Denial Of Service attack CVE-2014-3571. A memory leak can occur in the dtls1bufferrecord function under certain conditions. In particular this could occur if an...
