{"id":"UBUNTU-CVE-2020-1700","details":"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.","modified":"2026-04-22T14:09:16.510665Z","published":"2020-01-31T00:00:00Z","related":["USN-4304-1"],"upstream":["CVE-2020-1700"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2020-1700"},{"type":"ADVISORY","url":"https://ubuntu.com/security/notices/USN-4304-1"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2020-1700"}],"affected":[{"package":{"name":"ceph","ecosystem":"Ubuntu:18.04:LTS","purl":"pkg:deb/ubuntu/ceph@12.2.12-0ubuntu0.18.04.5?arch=source&distro=bionic"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"12.2.12-0ubuntu0.18.04.5"}]}],"versions":["12.2.0-0ubuntu1","12.2.1-0ubuntu1","12.2.2-0ubuntu1","12.2.2-0ubuntu2","12.2.4-0ubuntu1","12.2.4-0ubuntu1.1","12.2.7-0ubuntu0.18.04.1","12.2.8-0ubuntu0.18.04.1","12.2.8-0ubuntu0.18.04.2","12.2.11-0ubuntu0.18.04.1","12.2.11-0ubuntu0.18.04.2","12.2.12-0ubuntu0.18.04.1","12.2.12-0ubuntu0.18.04.2","12.2.12-0ubuntu0.18.04.3","12.2.12-0ubuntu0.18.04.4"],"ecosystem_specific":{"availability":"No subscription required","binaries":[{"binary_name":"ceph","binary_version":"12.2.12-0ubuntu0.18.04.5"},{"binary_name":"ceph-base","binary_version":"12.2.12-0ubuntu0.18.04.5"},{"binary_name":"ceph-common","binary_version":"12.2.12-0ubuntu0.18.04.5"},{"binary_name":"ceph-fuse","binary_version":"12.2.12-0ubuntu0.18.04.5"},{"binary_name":"ceph-mds","binary_version":"12.2.12-0ubuntu0.18.04.5"},{"binary_name":"ceph-mgr","binary_version":"12.2.12-0ubuntu0.18.04.5"},{"binary_name":"ceph-mon","binary_version":"12.2.12-0ubuntu0.18.04.5"},{"binary_name":"ceph-osd","binary_version":"12.2.12-0ubuntu0.18.04.5"},{"binary_name":"ceph-resource-agents","binary_version":"12.2.12-0ubuntu0.18.04.5"},{"binary_name":"ceph-test","binary_version":"12.2.12-0ubuntu0.18.04.5"},{"binary_name":"libcephfs-java","binary_version":"12.2.12-0ubuntu0.18.04.5"},{"binary_name":"libcephfs-jni","binary_version":"12.2.12-0ubuntu0.18.04.5"},{"binary_name":"libcephfs2","binary_version":"12.2.12-0ubuntu0.18.04.5"},{"binary_name":"librados2","binary_version":"12.2.12-0ubuntu0.18.04.5"},{"binary_version":"12.2.12-0ubuntu0.18.04.5","binary_name":"libradosstriper1"},{"binary_name":"librbd1","binary_version":"12.2.12-0ubuntu0.18.04.5"},{"binary_name":"librgw2","binary_version":"12.2.12-0ubuntu0.18.04.5"},{"binary_name":"python-ceph","binary_version":"12.2.12-0ubuntu0.18.04.5"},{"binary_name":"python-cephfs","binary_version":"12.2.12-0ubuntu0.18.04.5"},{"binary_name":"python-rados","binary_version":"12.2.12-0ubuntu0.18.04.5"},{"binary_name":"python-rbd","binary_version":"12.2.12-0ubuntu0.18.04.5"},{"binary_name":"python-rgw","binary_version":"12.2.12-0ubuntu0.18.04.5"},{"binary_name":"python3-ceph-argparse","binary_version":"12.2.12-0ubuntu0.18.04.5"},{"binary_name":"python3-cephfs","binary_version":"12.2.12-0ubuntu0.18.04.5"},{"binary_name":"python3-rados","binary_version":"12.2.12-0ubuntu0.18.04.5"},{"binary_name":"python3-rbd","binary_version":"12.2.12-0ubuntu0.18.04.5"},{"binary_name":"python3-rgw","binary_version":"12.2.12-0ubuntu0.18.04.5"},{"binary_name":"radosgw","binary_version":"12.2.12-0ubuntu0.18.04.5"},{"binary_name":"rbd-fuse","binary_version":"12.2.12-0ubuntu0.18.04.5"},{"binary_version":"12.2.12-0ubuntu0.18.04.5","binary_name":"rbd-mirror"},{"binary_version":"12.2.12-0ubuntu0.18.04.5","binary_name":"rbd-nbd"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2020/UBUNTU-CVE-2020-1700.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H"},{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H"},{"type":"Ubuntu","score":"medium"}]}
