Summary

Ceph is a distributed object, block, and file storage platform. In versions up to and including 19.2.3, using the argument `x-amz-copy-source` to put an object and specifying an empty string as its content leads to the RGW daemon crashing, resulting in a DoS attack. As of time of publication, no known patched versions exist.

Fencer Vulns keeps one entry per vulnerability: the CVE id wins, then GHSA, and records that alias each other are merged, except that two CVEs always keep separate entries. The same data is available as JSON.

CPEs and fixed versions use Anchore's correction of NVD's data: Added CPE configurations because not yet analyzed by NVD.
