    cURL, an URL transfer library, contains a heap buffer overflow in the
    function tftp_receive_packet() that receives data from a TFTP server.
    It calls recvfrom() with the default size for the buffer rather than
    with the size that was used to allocate it. Thus, the content that
    might overwrite the heap memory is entirely controlled by the server.
    
    For Debian 8 "Jessie", this problem has been fixed in version
    7.38.0-4+deb8u15.
    
    We recommend that you upgrade your curl packages.
