{"id":"CVE-2024-12243","summary":"Gnutls: gnutls impacted by inefficient der decoding in libtasn1 leading to remote dos","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":"2026-07-11T03:55:38.813233525Z","published":"2025-02-10T15:28:10.328Z","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"],"database_specific":{"cwe_ids":["CWE-407"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/12xxx/CVE-2024-12243.json","cna_assigner":"redhat"},"references":[{"type":"WEB","url":"https://access.redhat.com/downloads/content/package-browser/"},{"type":"WEB","url":"https://catalog.redhat.com/software/containers/"},{"type":"WEB","url":"https://cert-portal.siemens.com/productcert/html/ssa-082556.html"},{"type":"WEB","url":"https://cert-portal.siemens.com/productcert/html/ssa-202008.html"},{"type":"WEB","url":"https://lists.debian.org/debian-lts-announce/2025/02/msg00027.html"},{"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-2025:7076"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2025:8020"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2025:8385"},{"type":"ADVISORY","url":"https://access.redhat.com/security/cve/CVE-2024-12243"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/12xxx/CVE-2024-12243.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-12243"},{"type":"ADVISORY","url":"https://security.netapp.com/advisory/ntap-20250523-0002/"},{"type":"REPORT","url":"https://bugzilla.redhat.com/show_bug.cgi?id=2344615"},{"type":"REPORT","url":"https://gitlab.com/gnutls/gnutls/-/issues/1553"},{"type":"REPORT","url":"https://gitlab.com/gnutls/libtasn1/-/issues/52"},{"type":"PACKAGE","url":"https://gitlab.com/gnutls/gnutls/"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://gitlab.com/gnutls/gnutls","events":[{"introduced":"0"},{"introduced":"744169a4a5421f3d0be72c70e63e7de479606ced"},{"introduced":"df405c5e64874529b7b9dc1177165f03971dc196"},{"fixed":"40267b5e16b5b418d7781c1c92d160a9bb12925b"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"last_affected":"3.6.16"},{"introduced":"3.7.0"},{"last_affected":"3.7.11"},{"introduced":"3.8.0"},{"fixed":"3.8.8"}],"source":"AFFECTED_FIELD"}}],"versions":["3.8.7","3.8.6","3.8.5","3.8.4","3.8.3","3.8.2","3.8.1","3.8.0"],"database_specific":{"source":"https://storage.googleapis.com/osv-test-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"}]}
