    CVE ID         : CVE-2017-1000367
    Debian Bug     : 863731
    
    The Qualys Security team discovered that sudo, a program designed to
    provide limited super user privileges to specific users, does not
    properly parse "/proc/[pid]/stat" to read the device number of the tty
    from field 7 (tty_nr). A sudoers user can take advantage of this flaw on
    an SELinux-enabled system to obtain full root privileges.
    
    For the stable distribution (jessie), this problem has been fixed in
    version 1.8.10p3-1+deb8u4.
    
    We recommend that you upgrade your sudo packages.
