Description

This vulnerability allows local attackers to escalate privileges on affected installations of VMware Workstation. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability. The specific flaw exists within the Virtual Printer module. The issue results from the lack of proper validation of a user-supplied shared object file path prior to loading the file. An attacker can leverage this vulnerability to escalate privileges and execute code in the context of root.
