Debian Security Advisory
DLA-970-1 sudo -- LTS security update
- Date Reported:
- 30 May 2017
- Affected Packages:
- Security database references:
- In the Debian bugtracking system: Bug 863731.
In Mitre's CVE dictionary: CVE-2017-1000367.
- More information:
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.
