Package : open-vm-tools
Version : 2:10.3.10-1+deb10u4
CVE ID : CVE-2023-20867
Debian Bug : 1037546

open-vm-tools is a package that provides Open VMware Tools for virtual
machines hosted on VMware.

It was discovered that Open VM Tools incorrectly handled certain
authentication requests. A fully compromised ESXi host can force Open
VM Tools to fail to authenticate host-to-guest operations, impacting
the confidentiality and integrity of the guest virtual machine.

For Debian 10 buster, this problem has been fixed in version
2:10.3.10-1+deb10u4.

We recommend that you upgrade your open-vm-tools packages.

For the detailed security status of open-vm-tools please refer to
its security tracker page at:
