Package        : sudo
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.
