VMware announced on Tuesday that it has patched a serious privilege escalation vulnerability that can be exploited on Mac systems where Fusion, Remote Console or Horizon Client are installed.
The vulnerability, tracked as CVE-2020-3950 and classified as high severity, is related to the improper use of setuid binaries, and it impacts Fusion 11.x, VMRC 11.x and prior, and Horizon Client 5.x and prior.
VMware also informed customers on Tuesday that the Windows versions of Workstation and Horizon Client are affected by a low-severity denial-of-service vulnerability caused by a heap overflow bug in Cortado Thinprint.
"Attackers with non-administrative access to a guest VM with virtual printing enabled may exploit this issue to create a denial-of-service condition of the Thinprint service running on the system where Workstation or Horizon Client is installed," VMware said in its advisory.
Earlier this month, VMware announced that it 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.
