CVE number: CVE-2018-6971, CVE-2018-6972
1. Summary

3. Problem Description
a. VMware Horizon View Agent local information disclosure vulnerability
VMware Horizon View Agents contain a local information disclosure
vulnerability due to insecure logging of credentials in the
vmmsi.log file when an account other than the currently logged on
user is specified during installation (including silent
installations). Successful exploitation of this issue may allow low
privileged users access to the credentials specified during the
Horizon View Agent installation.
The Common Vulnerabilities and Exposures project (cve.mitre.org) has
assigned the identifier CVE-2018-6971 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.

============ ======= ======== ======== ============ ============
View Agent 7.x.x Windows Important 7.5.1* KB56631
*The Horizon View Agent 7.5.1 upgrade process will attempt to remove
vmmsi.log files which may contain installation credentials. This
process may not be effective if the temporary windows directory
(%TEMP%) was changed after installation or if these logs have been
collected by an external solution such as VMware vRealize Log
Insight or a similar 3rd party product. Please see KB56631 for
more details on manual cleanup.
b. ESXi, Workstation, and Fusion denial-of-service vulnerability
VMware ESXi, Workstation, and Fusion contain a denial-of-service
vulnerability due to NULL pointer dereference issue in RPC handler.
Successful exploitation of this issue may allow attackers with
normal user privileges to crash their VMs.
VMware would like to thank Hahna Latonick and Kevin Fujimoto working
with Trend Micro's Zero Day Initiative for reporting this issue to
us.
