Publication date

Overview

Sudo could be made to crash or escalate privileges.


Packages

Details

It was discovered that Sudo incorrectly handled the per-command chroot

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.
