Patch Radar priority: Routine. - Web page: https://patchblox.com/security/cve/CVE-2020-1700 - Priority: Routine - CVSS: n/a (Medium) - EPSS: 0.0244 - CISA KEV: not listed - Exploited (vendor report): no - Publicly disclosed: no - Published: Jan 30, 2020 ## Description 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. ## Where it's fixed | Platform | Product | Fixed in | Fix | Released | |---|---|---|---|---| | Linux | ceph Ubuntu 18.04.6 LTS (bionic) | 12.2.12-0ubuntu0.18.04.5 | [ceph
