{"id":"DEBIAN-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.","modified":"2026-09-01T16:04:22.580614889Z","published":"2017-12-05T18:29:00.227Z","upstream":["CVE-2017-17051"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2017-17051"}],"affected":[{"package":{"name":"nova","ecosystem":"Debian:12","purl":"pkg:deb/debian/nova?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2:16.0.3-6"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2017-17051.json"}},{"package":{"name":"nova","ecosystem":"Debian:13","purl":"pkg:deb/debian/nova?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2:16.0.3-6"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2017-17051.json"}},{"package":{"name":"nova","ecosystem":"Debian:14","purl":"pkg:deb/debian/nova?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2:16.0.3-6"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2017-17051.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:C/C:N/I:N/A:H"}]}
