ceph: A flaw was found in the way the Ceph RGW Beast front-end handles unexpected disconnects
CVE-2020-1700 is fixed in 31 products on 1 platform, first by ceph 12.2.12-0ubuntu0.18.04.5, released January 30, 2020. It is not reported as exploited. Patch Radar priority: Routine.
A flaw was found in the way the Ceph RGW Beast front-end handles unexpected disconnects. An authenticated attacker can abuse this flaw by making multiple disconnect attempts resulting in a permanent leak of a socket connection by radosgw. This flaw could lead to a denial of service condition by pile up of CLOSE_WAIT sockets, eventually leading to the exhaustion of available resources, preventing legitimate users from connecting to the system.
