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...

openssl lib32-openssl: multiple issues

CVE-2015-3193 insecure private key in connection with DHE There is a carry propagating bug in the x8664 Montgomery squaring procedure. No EC algorithms are affected. Analysis suggests that attacks against RSA and DSA as a result of this defect would be very difficult to perform and are not...

Vulnerability in OpenSSL - Certificate verify crash with missing PSS parameter

The signature verification routines will crash with a NULL pointer dereference if presented with an ASN.1 signature using the RSA PSS algorithm and absent mask generation function parameter. Since these routines are used to verify certificate signature algorithms this can be used to crash any...
