gdisk - GPT fdisk text-mode partitioning tool

Details

The potential for an out of bounds write due to a missing bounds
check was discovered to impact the sgdisk utility of GPT fdisk.
Exploitation requires the use of a maliciously formatted storage
device and could cause sgdisk to crash as well as possibly
allow for local privilege escalation.
