"The version of VMware Workstation installed on the remote host is 15.x. It is, therefore, affected by the following
vulnerabilities:

  - Multiple out-of-bounds read vulnerabilities in Cortado ThinPrint components JPEG2000 parser, EMR
    STRETCHDIBITS parser, and EMF Parser. A malicious actor with normal access to a virtual machine can
    exploit these issues to create a partial denial-of-service condition or to leak memory from TPView process
    running on the system where Workstation is installed. (CVE-2020-3986, CVE-2020-3987, CVE-2020-3988)

  - A denial of service (DoS) vulnerability due to an out-of-bounds write issue in a Cortado ThinPrint
    component. A malicious actor with normal access to a virtual machine can exploit this issue to create a
    partial denial-of-service condition on the system where Workstation is installed. Exploitation is only
    possible if virtual printing has been enabled. This feature is not enabled by default on Workstation.
    (CVE-2020-3989)

  - An information disclosure vulnerability due to an integer overflow issue in Cortado ThinPrint component. A
    malicious actor with normal access to a virtual machine can exploit this issue to leak memory from TPView
    process running on the system where Workstation is installed. Exploitation is only possible if virtual
    printing has been enabled. This feature is not enabled by default on Workstation. (CVE-2020-3990)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
