GHSA-C7JH-R37W-P7JC

Vulnerability from github – Published: 2022-07-16 00:00 – Updated: 2022-07-23 00:00

Details

This vulnerability allows local attackers to escalate privileges on affected installations of Parallels Desktop 16.5.1 (49187). An attacker must first obtain the ability to execute high-privileged code on the target guest system in order to exploit this vulnerability. The specific flaw exists within the HDAudio virtual device. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length buffer. An attacker can leverage this vulnerability to escalate privileges and execute arbitrary code in the context of the hypervisor. Was ZDI-CAN-14969.

Severity ?

8.2 (High)


                  
                    CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:C/C:H/I:H/A:H
