==========================================================================
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)
