    Package        : open-vm-tools
    Version        : 2:10.3.10-1+deb10u5
    CVE ID         : CVE-2023-20900
    Debian Bug     : 1050970

    A security vulnerability was found in the Open VMware Tools. A malicious actor
    that has been granted Guest Operation Privileges in a target virtual machine
    may be able to elevate their privileges if that target virtual machine has been
    assigned a more privileged Guest Alias.

    For Debian 10 buster, this problem has been fixed in version
    2:10.3.10-1+deb10u5.

    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:
