Description

This vulnerability allows local attackers to escalate privileges on affected installations of Parallels Desktop 15.1.4.

The specific flaw exists within the handling of network packets. The issue results from the lack of proper validation of user-supplied data, which can result in a memory corruption condition. An attacker can leverage this vulnerability to escalate privileges and execute code in the context of the hypervisor. Was ZDI-CAN-11253.
