Package        : ceph
Version        : 10.2.11-2+deb9u1
CVE ID         : CVE-2018-14662 CVE-2018-16846 CVE-2020-1760 CVE-2020-10753 
                 CVE-2021-3524
Debian Bug     : 921948 921947 956142 975300 988889

Several vulnerabilities were discovered in Ceph, a distributed storage
and file system.

CVE-2018-14662

     Authenticated ceph users with read only permissions could steal dm-crypt
     encryption keys used in ceph disk encryption.

CVE-2018-16846

     Authenticated ceph RGW users can cause a denial of service against OMAPs
     holding bucket indices.

CVE-2020-10753

     A flaw was found in the Red Hat Ceph Storage RadosGW (Ceph Object
     Gateway).
     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.

CVE-2020-1760

     A flaw was found in the Ceph Object Gateway, where it supports request
     sent by an anonymous user in Amazon S3. This flaw could lead to potential
     XSS attacks due to the lack of proper neutralization of untrusted input.

CVE-2021-3524

     A flaw was found in the Red Hat Ceph Storage RadosGW (Ceph Object Gateway)
     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.

For Debian 9 stretch, these problems have been fixed in version
10.2.11-2+deb9u1.

We recommend that you upgrade your ceph packages.
