CVE-2020-3988

Status: ModifiedMedium (6.1)—

VMware Workstation (15.x) and Horizon Client for Windows (5.x before 5.4.4) contain an out-of-bounds read vulnerability in Cortado ThinPrint component (JPEG2000 parser). A malicious actor with normal access to a virtual machine may be able to exploit these issues to create a partial denial-of-service condition or to leak memory from TPView process running on the system where Workstation or Horizon Client for Windows is installed.

CVSS

Exploitation probability (EPSS)

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).
