CVE-2016-0787

5.9 mediumEPSS 2.6%

Medium (5.9). EPSS 2.6% chance of exploitation in the next 30 days.

The diffie_hellman_sha256 function in kex.c in libssh2 before 1.7.0 improperly truncates secrets to 128 or 256 bits, which makes it easier for man-in-the-middle attackers to decrypt or intercept SSH sessions via unspecified vectors, aka a "bits/bytes confusion bug."
