    Package : libssh2
    CVE ID : CVE-2016-0787
    Debian Bug : 815662

    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 security, potentially allowing an
    eavesdropper with enough resources to decrypt or intercept SSH sessions.

    For the oldstable distribution (wheezy), this problem has been fixed
    in version 1.4.2-1.1+deb7u2.

    For the stable distribution (jessie), this problem has been fixed in
    version 1.4.3-4.1+deb8u1.

    We recommend that you upgrade your libssh2 packages.
