VMware Workstation (15.x) and Horizon Client for Windows (5.x before 5.4.4) contain an information disclosure vulnerability due to an integer overflow issue in Cortado ThinPrint component. A malicious actor with normal access to a virtual machine may be able to exploit this issue to leak memory from TPView process running on the system where Workstation or Horizon Client for Windows is installed. Exploitation is only possible if virtual printing has been enabled. This feature is not enabled by default on Workstation but it is enabled by default on Horizon Client.
CWE-125 - Out-of-Bounds Read
Out-of-bounds read is a vulnerability that allows access to memory beyond the authorized accessible location. Such a vulnerability compromises the confidentiality of the trusted environment in the application and enables an attacker to launch further attacks by leveraging the exposed information.
