{"id":"DEBIAN-CVE-2024-12133","details":"A flaw in libtasn1 causes inefficient handling of specific certificate data. When processing a large number of elements in a certificate, libtasn1 takes much longer than expected, which can slow down or even crash the system. This flaw allows an attacker to send a specially crafted certificate, causing a denial of service attack.","modified":"2026-09-15T09:02:54.492624356Z","published":"2025-02-10T16:15:37.260Z","upstream":["CVE-2024-12133"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2024-12133"}],"affected":[{"package":{"name":"libtasn1-6","ecosystem":"Debian:12","purl":"pkg:deb/debian/libtasn1-6?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"4.19.0-2+deb12u1"}]}],"versions":["4.19.0-2"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2024-12133.json"}},{"package":{"name":"libtasn1-6","ecosystem":"Debian:13","purl":"pkg:deb/debian/libtasn1-6?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"4.20.0-1"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2024-12133.json"}},{"package":{"name":"libtasn1-6","ecosystem":"Debian:14","purl":"pkg:deb/debian/libtasn1-6?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"4.20.0-1"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2024-12133.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:L"}]}
