{"id":"DEBIAN-CVE-2022-3996","details":"If an X.509 certificate contains a malformed policy constraint and policy processing is enabled, then a write lock will be taken twice recursively.  On some operating systems (most widely: Windows) this results in a denial of service when the affected process hangs.  Policy processing being enabled on a publicly facing server is not considered to be a common setup.  Policy processing is enabled by passing the `-policy' argument to the command line utilities or by calling the `X509_VERIFY_PARAM_set1_policies()' function.  Update (31 March 2023): The description of the policy processing enablement was corrected based on CVE-2023-0466.","modified":"2026-08-27T23:04:28.366427867Z","published":"2022-12-13T16:15:22.007Z","upstream":["CVE-2022-3996"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2022-3996"}],"affected":[{"package":{"name":"openssl","ecosystem":"Debian:12","purl":"pkg:deb/debian/openssl?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.0.7-2"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2022-3996.json"}},{"package":{"name":"openssl","ecosystem":"Debian:13","purl":"pkg:deb/debian/openssl?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.0.7-2"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2022-3996.json"}},{"package":{"name":"openssl","ecosystem":"Debian:14","purl":"pkg:deb/debian/openssl?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.0.7-2"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2022-3996.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"}]}
