{"id":"ALPINE-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":"2025-12-03T22:55:00.302559Z","published":"2025-02-10T16:15:37.260Z","upstream":["CVE-2024-12133"],"references":[{"type":"ADVISORY","url":"https://security.alpinelinux.org/vuln/CVE-2024-12133"}],"affected":[{"package":{"name":"libtasn1","ecosystem":"Alpine:v3.18","purl":"pkg:apk/alpine/libtasn1?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"4.20.0-r0"}]}],"versions":["1.8-r0","2.0-r0","2.1-r0","2.12-r0","2.13-r0","2.14-r0","2.2-r0","2.4-r0","2.5-r0","2.5-r1","2.6-r0","2.6-r1","2.6-r2","2.8-r0","2.8-r1","2.9-r0","2.9-r1","3.1-r0","3.2-r0","3.3-r0","3.4-r0","3.6-r0","4.1-r0","4.10-r0","4.10-r1","4.12-r0","4.12-r1","4.12-r2","4.13-r0","4.14-r0","4.15.0-r0","4.16.0-r0","4.16.0-r1","4.17.0-r0","4.18.0-r0","4.19.0-r0","4.19.0-r1","4.2-r0","4.4-r0","4.5-r0","4.6-r0","4.7-r0","4.8-r0","4.9-r0"],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2024-12133.json"}},{"package":{"name":"libtasn1","ecosystem":"Alpine:v3.19","purl":"pkg:apk/alpine/libtasn1?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"4.20.0-r0"}]}],"versions":["1.8-r0","2.0-r0","2.1-r0","2.12-r0","2.13-r0","2.14-r0","2.2-r0","2.4-r0","2.5-r0","2.5-r1","2.6-r0","2.6-r1","2.6-r2","2.8-r0","2.8-r1","2.9-r0","2.9-r1","3.1-r0","3.2-r0","3.3-r0","3.4-r0","3.6-r0","4.1-r0","4.10-r0","4.10-r1","4.12-r0","4.12-r1","4.12-r2","4.13-r0","4.14-r0","4.15.0-r0","4.16.0-r0","4.16.0-r1","4.17.0-r0","4.18.0-r0","4.19.0-r0","4.19.0-r1","4.19.0-r2","4.2-r0","4.4-r0","4.5-r0","4.6-r0","4.7-r0","4.8-r0","4.9-r0"],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2024-12133.json"}},{"package":{"name":"libtasn1","ecosystem":"Alpine:v3.20","purl":"pkg:apk/alpine/libtasn1?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"4.20.0-r0"}]}],"versions":["1.8-r0","2.0-r0","2.1-r0","2.12-r0","2.13-r0","2.14-r0","2.2-r0","2.4-r0","2.5-r0","2.5-r1","2.6-r0","2.6-r1","2.6-r2","2.8-r0","2.8-r1","2.9-r0","2.9-r1","3.1-r0","3.2-r0","3.3-r0","3.4-r0","3.6-r0","4.1-r0","4.10-r0","4.10-r1","4.12-r0","4.12-r1","4.12-r2","4.13-r0","4.14-r0","4.15.0-r0","4.16.0-r0","4.16.0-r1","4.17.0-r0","4.18.0-r0","4.19.0-r0","4.19.0-r1","4.19.0-r2","4.2-r0","4.4-r0","4.5-r0","4.6-r0","4.7-r0","4.8-r0","4.9-r0"],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2024-12133.json"}},{"package":{"name":"libtasn1","ecosystem":"Alpine:v3.21","purl":"pkg:apk/alpine/libtasn1?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"4.20.0-r0"}]}],"versions":["1.8-r0","2.0-r0","2.1-r0","2.12-r0","2.13-r0","2.14-r0","2.2-r0","2.4-r0","2.5-r0","2.5-r1","2.6-r0","2.6-r1","2.6-r2","2.8-r0","2.8-r1","2.9-r0","2.9-r1","3.1-r0","3.2-r0","3.3-r0","3.4-r0","3.6-r0","4.1-r0","4.10-r0","4.10-r1","4.12-r0","4.12-r1","4.12-r2","4.13-r0","4.14-r0","4.15.0-r0","4.16.0-r0","4.16.0-r1","4.17.0-r0","4.18.0-r0","4.19.0-r0","4.19.0-r1","4.19.0-r2","4.2-r0","4.4-r0","4.5-r0","4.6-r0","4.7-r0","4.8-r0","4.9-r0"],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2024-12133.json"}},{"package":{"name":"libtasn1","ecosystem":"Alpine:v3.22","purl":"pkg:apk/alpine/libtasn1?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"4.20.0-r0"}]}],"versions":["1.8-r0","2.0-r0","2.1-r0","2.12-r0","2.13-r0","2.14-r0","2.2-r0","2.4-r0","2.5-r0","2.5-r1","2.6-r0","2.6-r1","2.6-r2","2.8-r0","2.8-r1","2.9-r0","2.9-r1","3.1-r0","3.2-r0","3.3-r0","3.4-r0","3.6-r0","4.1-r0","4.10-r0","4.10-r1","4.12-r0","4.12-r1","4.12-r2","4.13-r0","4.14-r0","4.15.0-r0","4.16.0-r0","4.16.0-r1","4.17.0-r0","4.18.0-r0","4.19.0-r0","4.19.0-r1","4.19.0-r2","4.2-r0","4.4-r0","4.5-r0","4.6-r0","4.7-r0","4.8-r0","4.9-r0"],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2024-12133.json"}},{"package":{"name":"libtasn1","ecosystem":"Alpine:v3.23","purl":"pkg:apk/alpine/libtasn1?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"4.20.0-r0"}]}],"versions":["1.8-r0","2.0-r0","2.1-r0","2.12-r0","2.13-r0","2.14-r0","2.2-r0","2.4-r0","2.5-r0","2.5-r1","2.6-r0","2.6-r1","2.6-r2","2.8-r0","2.8-r1","2.9-r0","2.9-r1","3.1-r0","3.2-r0","3.3-r0","3.4-r0","3.6-r0","4.1-r0","4.10-r0","4.10-r1","4.12-r0","4.12-r1","4.12-r2","4.13-r0","4.14-r0","4.15.0-r0","4.16.0-r0","4.16.0-r1","4.17.0-r0","4.18.0-r0","4.19.0-r0","4.19.0-r1","4.19.0-r2","4.2-r0","4.4-r0","4.5-r0","4.6-r0","4.7-r0","4.8-r0","4.9-r0"],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2024-12133.json"}}],"schema_version":"1.7.3","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C
