Vulnerability Spotlight: VMWare Workstation DoS Vulnerability

Summary: Cisco Talos disclosed CVE-2018-6977, an exploitable denial-of-service vulnerability in VMware Workstation 14 (14.1.1.28517) found by Piotr Bania, located in the pixel shader the software uses. A malformed pixel shader supplied in text or binary form inside a VMware guest operating system can crash a process and cause a DoS, and the flaw can also be triggered through WebGL if the browser does not use ANGLE.
What's compelling: The trigger sits inside the guest, so a workload running in a VM can crash the host-side process without any external network path, and Talos issued Snort rules 46541 and 46542 because signature coverage is the fallback until the platform is patched.
