Security Advisory

1) Out-of-bounds read

Severity: Low

CVSSv3: 4.5 [CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:C/C:L/I:N/A:L/E:U/RL:O/RC:C] [PCI]

CVE-ID: CVE-2019-5522

CWE-ID: CWE-125 - Out-of-bounds Read

Description

The vulnerability allows a local user to gain access to potentially sensitive information.

The vulnerability exists due to a boundary condition within the vm3dmp driver, installed  with vmtools on Windows guest machines. A local non-privileged user of a Windows guest machine can use a specially crafted application to trigger out-of-bounds read and gain access to kernel memory on the same guest OS or perform denial of service attack against guest OS.

Mitigation

Install updates from vendor's website.
