There is no fixed version for libssh2
.
Overview
libssh2 is a client-side C library implementing the SSH2 protocol.
Affected versions of this package are vulnerable to Information Exposure. 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.
