Platform 17.0 (Wallaby).

2. Relevant releases/architectures:

Red Hat OpenStack Platform 17.0 - noarch

3. Description:

OpenStack Object Storage (swift) aggregates commodity servers to
 work together in clusters for reliable, redundant, and large-scale storage
of static objects. Objects are written to multiple hardware devices in the
data center, with the OpenStack software responsible for ensuring data
replication and integrity across the cluster. Storage clusters can scale
horizontally by adding new nodes, which are automatically configured.
Should a node fail, OpenStack works to replicate its content from other
active nodes. Because OpenStack uses software logic to ensure data
replication and distribution across different devices, inexpensive
commodity hard drives and servers can be used in lieu of more expensive
equipment.

Security Fix(es):

* Arbitrary file access through custom S3 XML entities (CVE-2022-47950)
