Type confusion

libssh before 0.7.3 improperly truncates ephemeral secrets generated for the 1 diffie-hellman-group1 and 2 diffie-hellman-group14 key exchange methods to 128 bits, which makes it easier for man-in-the-middle attackers to decrypt or intercept SSH sessions via unspecified vectors, aka a "bits/bytes...

Amazon Linux AMI : libssh2 (ALAS-2016-683)

A type confusion issue was found in the way libssh2 generated ephemeral secrets for the diffie-hellman-group1 and diffie-hellman-group14 key exchange methods. This would cause an SSHv2 Diffie-Hellman handshake to use significantly less secure random parameters. C Tenable Network Security, Inc. Th...

nss: Use-after-free in NSS during SSL connections in low memory (MFSA 2016-15)

A use-after-free flaw was found in the way NSS handled DHE Diffie–Hellman key exchange and ECDHE Elliptic Curve Diffie-Hellman key exchange handshake messages. A remote attacker could send a specially crafted handshake message that, when parsed by an application linked against NSS, would cause th...
