Doc Text:	A double-free vulnerability was found in Sudo in the per-command chroot feature. This flaw exists due to a boundary error when matching a sudoer rule that contains a per-command chroot directive (CHROOT=dir). By sending a specially-crafted request, a local privileged attacker can elevate privileges and execute arbitrary code on the system.	Story Points:	---
