Package : glance
Version : 2:17.0.0-5+deb10u1
CVE ID : CVE-2022-47951
Debian Bug : 1029563

An issue was discovered in Glance, OpenStack Image Registry and Delivery
Service - Daemons. 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
2:17.0.0-5+deb10u1.

We recommend that you upgrade your glance packages.
