Name of the Vulnerable Software and Affected Versions Ceph versions prior to 13.2.4

Description The issue exists due to insufficient input validation in the Ceph storage system. Exploitation of this issue can allow a remote attacker to cause a denial of service. Authenticated Ceph RGW users can cause this denial of service against OMAPs holding bucket indices.
