Security News > 2023 > April > VMware fixes critical flaws in virtualization software (CVE-2023-20869, CVE-2023-20870)
VMware has fixed one critical and three important flaws in its VMware Workstation and Fusion virtual user session software.
As explained by VMware, CVE-2023-20869 is a critical stack-based buffer-overflow vulnerability in the functionality for sharing host Bluetooth devices with the virtual machine, which allows a malicious actor with local administrative privileges to execute code as the virtual machine's VMX process running on the host.
CVE-2023-20871 - a local privilege escalation vulnerability - only affects VMware Fusion, and may allow a malicious actor with read/write access to the host OS to gain root access.
The first two vulnerabilities have been reported to VMware via Trend Micro's Zero Day Initiative.
The vulnerabilities affect VMware Workstation Pro v17.
Earlier this week VMware has patched two vulnerabilities in its VMware Aria Operations for Logs.
