 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:
