Package : sudo
Version : 1.8.10p3-1+deb8u6
CVE ID : CVE-2019-14287
Debian Bug : 942322
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.
