    Package        : libssh2
    CVE ID         : CVE-2015-1782
    Debian Bug     : 780249
    
    Mariusz Ziulek reported that libssh2, a SSH2 client-side library, was
    reading and using the SSH_MSG_KEXINIT packet without doing sufficient
    range checks when negotiating a new SSH session with a remote server. A
    malicious attacker could man in the middle a real server and cause a
    client using the libssh2 library to crash (denial of service) or
    otherwise read and use unintended memory areas in this process.
    
    For the stable distribution (wheezy), this problem has been fixed in
    version 1.4.2-1.1+deb7u1.
    
    We recommend that you upgrade your libssh2 packages.
