Package : cinder
Version : 2:13.0.7-1+deb10u2
CVE ID : CVE-2022-47951
Debian Bug : 1029562

An issue was discovered in OpenStack Cinder, a Block Storage service
for OpenStack. 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
2:13.0.7-1+deb10u2.

We recommend that you upgrade your cinder packages.
