CVE-2020-3948: VMware Fusion

High severity, CVSS 7.8. EPSS: 0.3% chance of exploitation in the next 30 days.

Linux Guest VMs running on VMware Workstation (15.x before 15.5.2) and Fusion (11.x before 11.5.2) contain a local privilege escalation vulnerability due to improper file permissions in Cortado Thinprint. Local attackers with non-administrative access to a Linux guest VM with virtual printing enabled may exploit this issue to elevate their privileges to root on the same guest VM.

Affected products

• VMware Fusion: from 11.0.0, before 11.5.2 (fixed in 11.5.2)
• VMware Workstation: from 15.0.0, before 15.5.2 (fixed in 15.5.2)
