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)
