Fedora 22 : libssh2-1.5.0-2.fc22 (2016-7942ee2cc5)

During the SSHv2 handshake when libssh2 is to get a suitable value for 'group order' in the Diffle Hellman negotiation, it would pass in number of bytes to a function that expected number of bits. This would result in the library generating numbers using only an 8th the number of random bits than...

Debian Security Advisory DSA 3487-1 (libssh2 - security update)

Andreas Schneider reported that libssh2, a SSH2 client-side library, 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...

libssh2: man-in-the-middle

There is a bits/bytes confusion bug resulting in generation of a significantly short ephemeral secret for the diffie-hellman-group1 and diffie-hellman-group14 key exchange methods. The resulting secret is 128 bits long, instead of the recommended sizes of 1024 and 2048 bits respectively. There ar...
