Public bug reported: Ubuntu Jammy cinder package version 2:20.3.1-0ubuntu1.4 [1] backported fix [2] for the LP#2059809 [3] (the CVE-2024-32498 fix). The upstream fix [2] calls the `format_inspector.detect_file_format` with the eleviated previlages [4], however the code in the Ubuntu package does not [5]. Instead it calls the `format_inspector.detect_file_format` without using privsep. That is causing the following error when creating qcow image from volume (using purestorage driver): 2024-10-28 09:45:28.849 2007342 ERROR oslo_messaging.rpc.server File "/usr/lib/python3/dist-packages/cinder/volume/manager.py", line 1744, in copy_volume_to_image 2024-10-28 09:45:28.849 2007342 ERROR oslo_messaging.rpc.server self.driver.copy_volume_to_image(context, volume, 2024-10-28 09:45:28.849 2007342 ERROR oslo_messaging.rpc.server File "/usr/lib/python3/dist-packages/cinder/volume/driver.py", line 919, in copy_volume_to_image 2024-10-28 09:45:28.849 2007342 ERROR oslo_messaging.rpc.server volume_utils.upload_volume(context, 2024-10-28 09:45:28.849 2007342 ERROR oslo_messaging.rpc.server File "/usr/lib/python3/dist-packages/cinder/volume/volume_utils.py", line 1341, in upload_volume 2024-10-28 09:45:28.849 2007342 ERROR oslo_messaging.rpc.server image_utils.upload_volume(context, image_service, image_meta, volume_path, 2024-10-28 09:45:28.849 2007342 ERROR oslo_messaging.rpc.server File "/usr/lib/python3/dist-packages/cinder/image/image_utils.py", line 1083, in upload_volume 2024-10-28 09:45:28.849 2007342 ERROR oslo_messaging.rpc.server data = qemu_img_info(volume_path, run_as_root=run_as_root) 2024-10-28 09:45:28.849 2007342 ERROR oslo_messaging.rpc.server File "/usr/lib/python3/dist-packages/cinder/image/image_utils.py", line 164, in qemu_img_info 2024-10-28 09:45:28.849 2007342 ERROR oslo_messaging.rpc.server inspector = format_inspector.detect_file_format(path) 2024-10-28 09:45:28.849 2007342 ERROR oslo_messaging.rpc.server File "/usr/lib/python3/dist-packages/cinder/image/format_inspector.py", line 921, in detect_file_format 2024-10-28 09:45:28.849 2007342 ERROR oslo_messaging.rpc.server with open(filename, 'rb') as f: 2024-10-28 09:45:28.849 2007342 ERROR oslo_messaging.rpc.server PermissionError: [Errno 13] Permission denied: '/dev/dm-0'
