Debian Linux Security Advisory 3867-1 - 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.

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.
