VMware has patched three serious vulnerabilities in its products, including a critical flaw in Workstation and Fusion that can be exploited to execute arbitrary code on the host from the guest operating system.
"Successful exploitation of this issue may lead to code execution on the host from the guest or may allow attackers to create a denial-of-service condition of the vmnetdhcp service running on the host machine," VMware said in an advisory.
Another vulnerability patched by VMware this week is CVE-2020-3948, a high-severity issue that allows local attackers with non-admin access to a Linux guest virtual machine with VMware Tools installed to escalate their privileges to root in the same VM. "Linux Guest VMs running on VMware Workstation and Fusion contain a local privilege escalation vulnerability due to improper file permissions in Cortado Thinprint," the virtualization giant explained.
The last vulnerability, tracked as CVE-2019-5543, has been described as a high-severity privilege escalation issue affecting Workstation for Windows, VMware Horizon Client for Windows, and Remote Console for Windows.
Patches for this flaw are included in Workstation for Windows 15.5.2, VMware Horizon Client for Windows 5.3.0, and VMRC for Windows 11.0.0.
