VMware ESXi, Workstation and Fusion contain a denial-of-service vulnerability in the shader functionality.

Successful exploitation of this issue may allow attackers with normal user privileges to create a denial-of-service condition on their own VM.

A local attacker with non-administrative access on the guest machine may exploit this issue to execute code on the host. This issue can only be exploited if a valid sound back-end is not connected."
