OpenSSL ASN.1 Signed Null Pointer Reference Vulnerability

OpenSSL is an open source implementation of SSL for strong encryption of network communications. OpenSSL has a security vulnerability that can be exploited by a remote attacker to send a special ASN.1 signed certificate that uses the RSA PSS algorithm but does not contain the MAST generator...

Updated openssl packages fix security vulnerability

If a client receives a ServerKeyExchange for an anonymous DH ciphersuite with the value of p set to 0 then a seg fault can occur leading to a possible denial of service attack CVE-2015-1794. Loic Jonas Etienne of Qnective AG discovered that the signature verification routines will crash with a NU...
