{"id":"CVE-2017-17051","details":"An issue was discovered in the default FilterScheduler in OpenStack Nova 16.0.3. By repeatedly rebuilding an instance with new images, an authenticated user may consume untracked resources on a hypervisor host leading to a denial of service, aka doubled resource allocations. This regression was introduced with the fix for OSSA-2017-005 (CVE-2017-16239); however, only Nova stable/pike or later deployments with that fix applied and relying on the default FilterScheduler are affected.","aliases":["GHSA-vq76-rxx3-4r4r"],"modified":"2026-04-10T03:57:53.259184Z","published":"2017-12-05T18:29:00.227Z","related":["SUSE-SU-2019:2219-1","SUSE-SU-2019:2267-1"],"references":[{"type":"ADVISORY","url":"http://www.securityfocus.com/bid/102102"},{"type":"ADVISORY","url":"https://review.openstack.org/521662"},{"type":"ADVISORY","url":"https://review.openstack.org/523214"},{"type":"ADVISORY","url":"https://security.openstack.org/ossa/OSSA-2017-006.html"},{"type":"REPORT","url":"https://launchpad.net/bugs/1732976"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/openstack/nova","events":[{"introduced":"0"},{"last_affected":"3f63d057a64b688b66ff1903c1afc4d97ba6df6d"}],"database_specific":{"versions":[{"introduced":"0"},{"last_affected":"16.0.3"}]}}],"versions":["0.9.0","12.0.0.0b1","12.0.0.0b2","12.0.0.0b3","12.0.0.0rc1","12.0.0a0","13.0.0.0b1","13.0.0.0b2","13.0.0.0b3","13.0.0.0rc1","14.0.0.0b1","14.0.0.0b2","14.0.0.0b3","14.0.0.0rc1","15.0.0.0b1","15.0.0.0b2","15.0.0.0b3","15.0.0.0rc1","16.0.0","16.0.0.0b1","16.0.0.0b2","16.0.0.0b3","16.0.0.0rc1","16.0.0.0rc2","16.0.1","16.0.2","16.0.3","2010.1","2011.1","2011.1rc1","2011.2","2011.2gamma1","2011.2rc1","2013.1.rc1","2013.2.b3","2013.2.rc1","2014.1.b1","2014.1.b2","2014.1.b3","2014.1.rc1","2014.2.b1","2014.2.b2","2014.2.b3","2014.2.rc1","2015.1.0b1","2015.1.0b2","2015.1.0b3","2015.1.0rc1","diablo-1","essex-1","folsom-1","folsom-2"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2017-17051.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:C/C:N/I:N/A:H"}]}
