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 what were intended: 128 or 256 bits instead of 1023 or 2047
Using such drastically reduced amount of random bits for Diffie Hellman weakened the handshake security significantly.
The Common Vulnerabilities and Exposures (CVE) project has assigned the name CVE-2016-0787 to this issue.
