To take advantage of these flaws, an attacker must have physical access to the computer system and employ a custom-crafted USB device or smart card to manipulate responses to APDUs. This manipulation can potentially allow \r\ncompromise key generation, certificate loading, and other card management operations during enrollment.","epss":{"date":"2026-11-06","percentile":0.70953,"score":0.01318},"exploits":[],"kev":null,"metrics":[{"score":5.4,"severity":"medium","source":"CNA: redhat","vector":"CVSS:3.1/AV:P/AC:L/PR:N/UI:R/S:U/C:L/I:L/A:H","version":"3.1"}],"modifiedAt":1793996792692,"publishedAt":1699289923029,"references":[{"source":"CNA: redhat","tags":["vendor-advisory","x_refsource_REDHAT"],"url":"https://access.redhat.com/errata/RHSA-2023:7876"},{"source":"CNA: redhat","tags":["vendor-advisory","x_refsource_REDHAT"],"url":"https://access.redhat.com/errata/RHSA-2023:7879"},{"source":"CNA: redhat","tags":["vdb-entry","x_refsource_REDHAT"],"url":"https://access.redhat.com/security/cve/CVE-2023-40661"},{"source":"CNA: redhat","tags":["issue-tracking","x_refsource_REDHAT"],"url":"https://bugzilla.redhat.com/show_bug.cgi?id=2240913"},{"source":"CNA: redhat","tags":[],"url":"https://github.com/OpenSC/OpenSC/issues/2792#issuecomment-1674806651"},{"source":"CNA: redhat","tags":[],"url":"https://github.com/OpenSC/OpenSC/releases/tag/0.24.0-rc1"},{"source":"CNA: redhat","tags":[],"url":"https://github.com/OpenSC/OpenSC/wiki/OpenSC-security-advisories"},{"source":"ADP: CVE","tags":["x_transferred"],"url":"http://www.openwall.com/lists/oss-security/2023/12/13/3"},{"source":"ADP: CVE","tags":["vendor-advisory","x_refsource_REDHAT","x_transferred"],"url":"https://access.redhat.com/errata/RHSA-2023:7876"},{"source":"ADP: CVE","tags":["vendor-advisory","x_refsource_REDHAT","x_transferred"],"url":"https://access.redhat.com/errata/RHSA-2023:7879"},{"source":"ADP: CVE","tags":["vdb-entry","x_refsource_REDHAT","x_transferred"],"url":"https://access.redhat.com/security/cve/CVE-2023-40661"},{"source":"ADP: CVE","tags":["issue-tracking","x_refsource_REDHAT","x_transferred"],"url":"https://bugzilla.redhat.com/show_bug.cgi?id=2240913"},{"source":"ADP: CVE","tags":["x_transferred"],"url":"https://github.com/OpenSC/OpenSC/issues/2792#issuecomment-1674806651"},{"source":"ADP: CVE","tags":["x_transferred"],"url":"https://github.com/OpenSC/OpenSC/releases/tag/0.24.0-rc1"},{"source":"ADP: CVE","tags":["x_transferred"],"url":"https://github.com/OpenSC/OpenSC/wiki/OpenSC-security-advisories"},{"source":"ADP: CVE","tags":["x_transferred"],"url":"https://lists.debian.org/debian-lts-announce/2023/11/msg00024.html"},{"source":"ADP: CVE","tags":["x_transferred"],"url":"https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/3CPQOMCDWFRBMEFR5VK4N5MMXXU42ODE/"},{"source":"ADP: CVE","tags":["x_transferred"],"url":"https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/GLYEFIBBA37TK3UNMZN5NOJ7IWCIXLQP/"},{"source":"ADP: CVE","tags":[],"url":"https://lists.debian.org/debian-lts-announce/2024/12/msg00026.html"}],"remediation":[],"revision":"9b3836dd89bde48c82d2e5517e6ba2a9490c0ffaefdfcc9c899314b7ffeae7f3","sources":[{"modifiedAt":1793996792692,"name":"CNA: redhat","retrievedAt":1793999307875,"url":"https://www.cve.org/CVERecord?id=CVE-2023-40661"},{"modifiedAt":null,"name":"FIRST EPSS","retrievedAt":1793999328937,"url":"https://api.first.org/data/v1/epss?cve=CVE-2023-40661"}],"ssvc":null,"status":"published","title":"Opensc: multiple memory issues with pkcs15-init (enrollment tool)","updatedAt":1793999328937}
