{"id":"DEBIAN-CVE-2023-34323","details":"When a transaction is committed, C Xenstored will first check the quota is correct before attempting to commit any nodes.  It would be possible that accounting is temporarily negative if a node has been removed outside of the transaction.  Unfortunately, some versions of C Xenstored are assuming that the quota cannot be negative and are using assert() to confirm it.  This will lead to C Xenstored crash when tools are built without -DNDEBUG (this is the default).","modified":"2026-09-15T09:02:42.761169385Z","published":"2024-01-05T17:15:08.493Z","upstream":["CVE-2023-34323"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2023-34323"}],"affected":[{"package":{"name":"xen","ecosystem":"Debian:12","purl":"pkg:deb/debian/xen?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"4.17.2+76-ge1f9cb16e2-1~deb12u1"}]}],"versions":["4.17.1+2-gb773c48e36-1","4.17.2+55-g0b56bed864-1","4.17.2-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2023-34323.json"}},{"package":{"name":"xen","ecosystem":"Debian:13","purl":"pkg:deb/debian/xen?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"4.17.2+55-g0b56bed864-1"}]}],"ecosystem_specific":{"urgency":"unimportant"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2023-34323.json"}},{"package":{"name":"xen","ecosystem":"Debian:14","purl":"pkg:deb/debian/xen?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"4.17.2+55-g0b56bed864-1"}]}],"ecosystem_specific":{"urgency":"unimportant"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2023-34323.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H"}]}
