{"id":"CVE-2024-12243","details":"A flaw was found in GnuTLS, which relies on libtasn1 for ASN.1 data processing. Due to an inefficient algorithm in libtasn1, decoding certain DER-encoded certificate data can take excessive time, leading to increased resource consumption. This flaw allows a remote attacker to send a specially crafted certificate, causing GnuTLS to become unresponsive or slow, resulting in a denial-of-service condition.","modified":"2026-04-16T04:33:20.452920236Z","published":"2025-02-10T16:15:37.423Z","related":["ALSA-2025:4051","ALSA-2025:7076","SUSE-SU-2025:00764-1","SUSE-SU-2025:0727-1","SUSE-SU-2025:0728-1","SUSE-SU-2025:0764-1","SUSE-SU-2025:0765-1","SUSE-SU-2025:0766-1","SUSE-SU-2025:0767-1","SUSE-SU-2025:20157-1","SUSE-SU-2025:20297-1","openSUSE-SU-2025:14835-1"],"references":[{"type":"WEB","url":"https://access.redhat.com/security/cve/CVE-2024-12243"},{"type":"WEB","url":"https://lists.debian.org/debian-lts-announce/2025/02/msg00027.html"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2025:7076"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2025:8020"},{"type":"ADVISORY","url":"https://security.netapp.com/advisory/ntap-20250523-0002/"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2025:17361"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2025:4051"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2025:8385"},{"type":"REPORT","url":"https://bugzilla.redhat.com/show_bug.cgi?id=2344615"},{"type":"REPORT","url":"https://gitlab.com/gnutls/libtasn1/-/issues/52"}],"affected":[{"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2024-12243.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L"}]}
