USN-5908-1: Sudo vulnerability

Ubuntu Security Notice USN-5908-1
March 02, 2023

sudo vulnerability

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 22.10
- Ubuntu 22.04 LTS


Sudo could be made to crash or escalate privileges.

Software Description:
- sudo: Provide limited super user privileges to specific users


It was discovered that Sudo incorrectly handled the per-command chroot
feature. In certain environments where Sudo is configured with a rule that
contains a CHROOT setting, a local attacker could use this issue to cause
Sudo to crash, resulting in a denial of service, or possibly escalate

Update instructions:

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

Ubuntu 22.10:
sudo 1.9.11p3-1ubuntu1.2
sudo-ldap 1.9.11p3-1ubuntu1.2

Ubuntu 22.04 LTS:
sudo 1.9.9-1ubuntu2.3
sudo-ldap 1.9.9-1ubuntu2.3

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