DLA-1964-1 sudo -- LTS security update

Date Reported:

17 Oct 2019

Affected Packages:

sudo

Vulnerable:

Yes

Security database references:

In the Debian bugtracking system: Bug 942322.
In Mitre's CVE dictionary: CVE-2019-14287.

More information:

In sudo, a program that provides limited super user privileges to specific users, an attacker with access to a Runas ALL sudoer account can bypass certain policy blacklists and session PAM modules, and can cause incorrect logging, by invoking sudo with a crafted user ID. For example, this allows bypass of (ALL,!root) configuration for a "sudo -u#-1" command.

See https://www.sudo.ws/alerts/minus_1_uid.html for further information.

For Debian 8 Jessie, this problem has been fixed in version 1.8.10p3-1+deb8u6.

We recommend that you upgrade your sudo packages.
