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

- Ubuntu 25.04
- Ubuntu 24.10
- Ubuntu 24.04 LTS
- Ubuntu 22.04 LTS

Summary:

Several security issues were fixed in Sudo.

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

Details:

Rich Mirch discovered that Sudo incorrectly handled the host option. In
environments where per-host rules are configured in the sudoers file, a
local attacker could use this issue to bypass the host restrictions.
(CVE-2025-32462)

Rich Mirch discovered that Sudo incorrectly handled the chroot option. In
environments where the sudoers file is configured to allow the chroot
option, a local attacker could use this issue to run arbitrary commands as
root. This issue only applied to Ubuntu 24.04 LTS, Ubuntu 24.10, and
Ubuntu 25.04. (CVE-2025-32463)

Update instructions:

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

Ubuntu 25.04
sudo 1.9.16p2-1ubuntu1.1
