Fixed In Version: sudo 1.9.13p2
Doc Type: If docs needed, set a value
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.
