VMSA-2019-0012 : Out-of-bounds pixel shader vulnerabilities
Critical Nessus Plugin ID 127807
SynopsisThe remote VMware ESXi host is missing one or more security-related patches.
DescriptionPixel shader vulnerabilities
VMware ESXi, Workstation and Fusion contain out-of-bounds read/write vulnerabilities in the pixel shader functionality.
Exploitation of these issues require an attacker to have access to a virtual machine with 3D graphics enabled. It is not enabled by default on ESXi and is enabled by default on Workstation and Fusion.
Successful exploitation of the out-of-bounds read issue (CVE-2019-5521) may lead to information disclosure or may allow attackers with normal user privileges to create a denial-of-service condition on the host.
The out-of-bounds write issue (CVE-2019-5684) can be exploited only if the host has an affected NVIDIA graphics driver. Successful exploitation of this issue may lead to code execution on the host.
Customers should check NVIDIA security advisory for additional information.
