3. Problem Description
a. V4H and V4PA desktop agent privilege escalation vulnerability
The V4H and V4PA desktop agents contain a privilege escalation vulnerability.
Successful exploitation of this issue could result in a low privileged windows
user escalating their privileges to SYSTEM.
VMware would like to thank Martin Lemay for reporting this issue to us.
The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned
the identifier CVE-2017-4946 to this issue.
Column 5 of the following table lists the action required to remediate the
vulnerability in each release, if a solution is available.
VMware Product Product Version Running on Severity Replace with/ Apply Patch Mitigation/ Workaround
V4H 6.x Windows Important 6.5.1* KB52195
V4PA 6.x Windows Important 6.5.1 KB52195
* This agent is also bundled with Horizon 7.4.
b. Out-of-bounds read issue via Cortado ThinPrint
VMware Workstation and Horizon View Client contain an out-of-bounds read
vulnerability in TPView.dll. On Workstation, this issue in conjunction with
other bugs may allow a guest to leak information from host or may allow for
a Denial of Service on the Windows OS that runs Workstation. In the case of a
Horizon View Client, this issue in conjunction with other bugs may allow a
View desktop to leak information from host or may allow for a Denial of Service
on the Windows OS that runs the Horizon View Client.
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 View.
VMware would like to thank Yakun Zhang of McAfee for reporting this issue to
us.
The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned
