VMSA-2018-0018 : VMware Horizon View Agent, VMware ESXi, Workstation, and Fusion updates resolve multiple security issues

Medium Nessus Plugin ID 111350

Synopsis

The remote VMware ESXi host is missing one or more security-related patches.

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.

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.

The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the identifier CVE-2018-6972 to this issue.
