Ephemeral Secrets Truncation Vulnerability in libssh

CVE-2016-0739 · MEDIUM Severity

AV:N/AC:M/AU:N/C:P/I:N/A:N

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 confusion bug."
