A vulnerability, which was classified as problematic, was found in VMware ESXi, Workstation and Fusion (Virtualization Software) (the affected version unknown). Affected is an unknown part of the component 3d Rendering Shader. The manipulation with an unknown input leads to a resource consumption vulnerability. CWE is classifying the issue as CWE-400. The product does not properly control the allocation and maintenance of a limited resource, thereby enabling an actor to influence the amount of resources consumed, eventually leading to the exhaustion of available resources. This is going to have an impact on availability. CVE summarizes:

VMware ESXi (6.7, 6.5, 6.0), Workstation (15.x and 14.x) and Fusion (11.x and 10.x) contain a denial-of-service vulnerability due to an infinite loop in a 3D-rendering shader. Successfully exploiting this issue may allow an attacker with normal user privileges in the guest to make the VM unresponsive, and in some cases, possibly result other VMs on the host or the host itself becoming unresponsive.

The bug was discovered 10/09/2018. The weakness was shared 10/09/2018 by Piotr Bania with Cisco Talos (Website). The advisory is shared for download at securitytracker.com. This vulnerability is traded as CVE-2018-6977 since 02/13/2018. The exploitability is told to be easy. The attack needs to be approached locally. The exploitation doesn't require any form of authentication. There are neither technical details nor an exploit publicly available. The current price for an exploit might be approx. USD $0-$5k (estimation calculated on 05/23/2023).

There is no information about possible countermeasures known. It may be suggested to replace the affected object with an alternative product.
