VMware has released security updates to fix critical and high severity vulnerabilities in VMware ESXi, Workstation, Fusion, and Cloud Foundation, allowing for code execution and privilege escalation.
One of the security bugs, with a critical severity rating and tracked as CVE-2020-4004, allows attackers with local administrative privileges on a virtual machine to abuse a use-after-free vulnerability in the XHCI USB controller of VMware ESXi, Workstation, and Fusion.
A second vulnerability, tracked as CVE-2020-4005 and rated as high severity, enables attackers to abuse a high severity VMware ESXi privilege escalation bug in the way system calls are managed to escalate privileges.
VMware has also issued security updates to address CVE-2020-4005 in all vulnerable VMware ESXi versions.
The company is still working on releasing fixed versions for the VMware Cloud Foundation of ESXi during the coming days.
