USN-4154-1: Sudo vulnerability

14 October 2019

Sudo could be made to run commands as root if it called with a specially crafted user ID.



  • sudo - Provide limited super user privileges to specific users


Joe Vennix discovered that Sudo incorrectly handled
certain user IDs. An attacker could potentially exploit this
to execute arbitrary commands as the root user.

Update instructions

The problem can be corrected by updating your system to the following package versions:

Ubuntu 19.04
Ubuntu 18.04
Ubuntu 16.04
Ubuntu 14.04
Ubuntu 12.04

In general, a standard system update will make all the necessary changes.
