VMware's latest security advisory discloses three vulnerabilities spread out among five products. The most significant of this trio is an "important" time-of-check time-of-use (TOCTOU) flaw in the service opener of Fusion, VMRC and Horizon Client that can be locally exploited to escalate privileges to root.
Officially designated CVE-2020-3957, the bug was assigned a CVSSv3 base score of 7.3, and has so far been fixed in version 11.5.5 of Fusion. Patches for VMRC and Horizon Client are still forthcoming, however.
Vmware has also issued fixes for a denial-of-service vulnerability (CVE-2020-3958) in the shader functionality of ESXi, Workstation and Fusion and a memory leak vulnerability (CVE-2020-3959) in the VMCI module of ESXi, Workstation and Fusion.
