Package : nova
Version : 2:18.1.0-6+deb10u2
CVE ID : CVE-2022-47951
Debian Bug : 1029561

An issue was discovered in Nova, an OpenStack project that provides a
way to provision compute instances (aka virtual servers). By supplying
a specially created VMDK flat image that references a specific backing
file path, an authenticated user may convince systems to return a copy
of that file's contents from the server, resulting in unauthorized
access to potentially sensitive data.

For Debian 10 buster, this problem has been fixed in version

We recommend that you upgrade your nova packages.
