MGASA-2016-0392 Updated libssh2 packages fix security vulnerability

Andreas Schneider reported that libssh2 passes the number of bytes to a function that expects number of bits during the SSHv2 handshake when libssh2 is to get a suitable value for 'group order' in the Diffie-Hellman negotiation. This weakens significantly the handshake security, potentially...

CVE-2016-7055

There is a carry propagating bug in the Broadwell-specific Montgomery multiplication procedure in OpenSSL 1.0.2 and 1.1.0 before 1.1.0c that handles input lengths divisible by, but longer than 256 bits. Analysis suggests that attacks against RSA, DSA and DH private keys are impossible. This is...
