sudo vulnerability
==========================================================================

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

- Ubuntu 25.10
- Ubuntu 24.04 LTS
- Ubuntu 22.04 LTS

Summary:

Sudo could be made to run programs as an administrator.

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

Details:

It was discovered that Sudo incorrectly checked return codes when dropping
privileges to run the mailer. A local attacker could possibly use this
issue to escalate privileges.

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

  sudo                            1.9.17p2-1ubuntu1.1

Ubuntu 24.04 LTS
  sudo                            1.9.15p5-3ubuntu5.24.04.2
  sudo-ldap                       1.9.15p5-3ubuntu5.24.04.2

Ubuntu 22.04 LTS
  sudo                            1.9.9-1ubuntu2.6
