Hi,

The following vulnerability was published for ceph.

CVE-2021-3524[0]:
| A flaw was found in the Red Hat Ceph Storage RadosGW (Ceph Object
| Gateway) in versions before 14.2.21. The vulnerability is related to
| the injection of HTTP headers via a CORS ExposeHeader tag. The newline
| character in the ExposeHeader tag in the CORS configuration file
| generates a header injection in the response when the CORS request is
| made. In addition, the prior bug fix for CVE-2020-10753 did not
| account for the use of \r as a header separator, thus a new flaw has
| been created.


If you fix the vulnerability please also make sure to include the
CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
