CVE-2024-40767: [OSSA-2024-002] OpenStack Nova: Incomplete file access fix and gssion for QCOW2 backing files and VMDK flat descriptors (CVE-2024-40767)
First published: Wed Jul 10 2024(Updated: )
Arnaud Morin (OVH) reported a vulnerability in Nova. By supplying a raw format image which is actually a specially crafted QCOW2 image with a backing file path or VMDK flat image with a descriptor file path, an authenticated user may convince systems to return a copy of the referenced file’s contents from the server resulting in unauthorized access to potentially sensitive data. All Nova deployments are affected.
