VMware Security Advisory

Advisory ID: VMSA-2018-0005
Severity: Critical
Synopsis: VMware Workstation, and Fusion updates resolve use-after
-free and integer-overflow vulnerabilities
Issue date: 2018-01-10
Updated on: 2018-01-10 (Initial Advisory)
CVE number: CVE-2017-4949, CVE-2017-4950

1. Summary

VMware Workstation, and Fusion updates resolve use-after-free and
integer-overflow vulnerabilities

2. Relevant Products

VMware Workstation Pro / Player (Workstation)
VMware Fusion Pro / Fusion (Fusion)

3. Problem Description

a. Use-after-free vulnerability in VMware NAT service

VMware Workstation and Fusion contain a use-after-free vulnerability
in VMware NAT service when IPv6 mode is enabled. This issue may
allow a guest to execute code on the host.

Note: IPv6 mode for VMNAT is not enabled by default.

VMware would like to thank WenQunWang of Tencent’s Xuanwu LAB for
reporting this issue to us.

The Common Vulnerabilities and Exposures project (cve.mitre.org) has
assigned the identifier CVE-2017-4949 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.

Fusion 10.x OS X Critical 10.1.1 None
Fusion 8.x OS X Critical 8.5.10 None

b. Integer-overflow vulnerability in VMware NAT service

VMware Workstation and Fusion contain an integer overflow
vulnerability in VMware NAT service when IPv6 mode is enabled. This
issue may lead to an out-of-bound read which can then be used to
execute code on the host in conjunction with other issues.

Note: IPv6 mode for VMNAT is not enabled by default.

VMware would like to thank WenQunWang of Tencent’s Xuanwu LAB for
reporting this issue to us.

The Common Vulnerabilities and Exposures project (cve.mitre.org) has
