Alert: VMware Releases Critical Security Updates

Attention, VMware users: New updates are now available to address critical security vulnerabilities in the following products: Fusion, Workstation Pro, ESXi and vCenter Server.

ESXi, Workstation and Fusion have an out-of-bounds write vulnerability in a Super Video Graphics Array (SVGA) device. This vulnerability would give guests the ability to execute code on the host.

The issue, which is being marked as “critical,” has been labeled CVE-2017-4924. It affects the following versions of VMware:

  • ESXi v. 6.5 (but not 6.0 or 5.5)
  • Workstation 12.x
  • Fusion 8.x

A NULL pointer dereference vulnerability has also been discovered that can be exploited when handling guest RPC requests. This could enable hackers with normal user privileges to take down virtual systems.

What's more, a moderately-severe bug has also been reported in the following versions of VMware:

  • ESXi v. 6.0 and 6.5
  • Workstation 12.x
  • Fusion 8.x

Users are now strongly encouraged to take immediate action and patch the above-mentioned systems. No workarounds are available.
