    Jann Horn discovered that the ptrace subsystem in the Linux kernel
    mishandles the management of the credentials of a process that wants
    to create a ptrace relationship, allowing a local user to obtain root
    privileges under certain scenarios.
    
    For Debian 8 "Jessie", this problem has been fixed in version
    4.9.168-1+deb9u4~deb8u1.
    
    We recommend that you upgrade your linux-4.9 packages.
