VMSA-2019-0006 : VMware ESXi, Workstation and Fusion updates address multiple out-of-bounds read vulnerabilities

medium Nessus Plugin ID 124192
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

Synopsis

The remote VMware ESXi host is missing one or more security-related patches.

Description

a. VMware ESXi, Workstation and Fusion vertex shader out-of-bounds read vulnerability

VMware ESXi, Workstation and Fusion updates address an out-of-bounds vulnerability with the vertex shader functionality. Exploitation of this issue requires an attacker to have access to a virtual machine with 3D graphics enabled. Successful exploitation of this issue may lead to information disclosure or may allow attackers with normal user privileges to create a denial-of-service condition on their own VM. The workaround for this issue involves disabling the 3D-acceleration feature. This feature is not enabled by default on ESXi and is enabled by default on Workstation and Fusion.
VMware would like to thank Piotr Bania of Cisco Talos for reporting this issue to us.
The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the identifier CVE-2019-5516 to this issue.

b. VMware ESXi, Workstation and Fusion multiple shader translator out-of-bounds read vulnerabilities

VMware ESXi, Workstation and Fusion contain multiple out-of-bounds read vulnerabilities in the shader translator. Exploitation of these issues requires an attacker to have access to a virtual machine with 3D graphics enabled. Successful exploitation of these issues may lead to information disclosure or may allow attackers with normal user privileges to create a denial-of-service condition on their own VM. The workaround for these issues involves disabling the 3D-acceleration feature. This feature is not enabled by default on ESXi and is enabled by default on Workstation and Fusion.

VMware would like to thank RanchoIce of Tencent Security ZhanluLab for reporting these issues to us.

The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the identifier CVE-2019-5517 to these issues.

c. VMware ESXi, Workstation and Fusion out-of-bounds read vulnerability

VMware ESXi, Workstation and Fusion updates address an out-of-bounds read vulnerability. Exploitation of this issue requires an attacker to have access to a virtual machine with 3D graphics enabled.
Successful exploitation of this issue may lead to information disclosure. The workaround for this issue involves disabling the 3D-acceleration feature. This feature is not enabled by default on ESXi and is enabled by default on Workstation and Fusion.

VMware would like to thank instructor working with Trend Micro's Zero Day Initiative for reporting this issue to us.
