Description

Package : sudo Version : 1.8.5p2-1+nmu3+deb7u3 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 Debian 7 "Wheezy", this problem has been fixed in version 1.8.5p2-1+nmu3+deb7u3.

For Debian 8 "Jessie", this problem has been fixed in version 1.8.10p3-1+deb8u4.

We recommend that you upgrade your sudo packages.
