USN-5908-1

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 privileges.
