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."}],"affected":[{"versions":[{"status":"affected","version":"0","lessThan":"0.24.0","versionType":"semver"}],"packageName":"OpenSC","collectionURL":"https://github.com/OpenSC/OpenSC","defaultStatus":"unaffected"},{"vendor":"Red Hat","product":"Red Hat Enterprise Linux 8","collectionURL":"https://access.redhat.com/downloads/content/package-browser/","packageName":"opensc","defaultStatus":"affected","versions":[{"version":"0:0.20.0-7.el8_9","lessThan":"*","versionType":"rpm","status":"unaffected"}],"cpes":["cpe:/o:redhat:enterprise_linux:8::baseos"]},{"vendor":"Red Hat","product":"Red Hat Enterprise Linux 9","collectionURL":"https://access.redhat.com/downloads/content/package-browser/","packageName":"opensc","defaultStatus":"affected","versions":[{"version":"0:0.23.0-3.el9_3","lessThan":"*","versionType":"rpm","status":"unaffected"}],"cpes":["cpe:/o:redhat:enterprise_linux:9::baseos"]},{"vendor":"Red Hat","product":"Red Hat Enterprise Linux 7","collectionURL":"https://access.redhat.com/downloads/content/package-browser/","packageName":"opensc","defaultStatus":"unknown","cpes":["cpe:/o:redhat:enterprise_linux:7"]}],"references":[{"url":"https://access.redhat.com/errata/RHSA-2023:7876","name":"RHSA-2023:7876","tags":["vendor-advisory","x_refsource_REDHAT"]},{"url":"https://access.redhat.com/errata/RHSA-2023:7879","name":"RHSA-2023:7879","tags":["vendor-advisory","x_refsource_REDHAT"]},{"url":"https://access.redhat.com/security/cve/CVE-2023-40661","tags":["vdb-entry","x_refsource_REDHAT"]},{"url":"https://bugzilla.redhat.com/show_bug.cgi?id=2240913","name":"RHBZ#2240913","tags":["issue-tracking","x_refsource_REDHAT"]},{"url":"https://github.com/OpenSC/OpenSC/issues/2792#issuecomment-1674806651"},{"url":"https://github.com/OpenSC/OpenSC/releases/tag/0.24.0-rc1"},{"url":"https://github.com/OpenSC/OpenSC/wiki/OpenSC-security-advisories"}],"datePublic":"2023-09-25T00:00:00.000Z","problemTypes":[{"descriptions":[{"cweId":"CWE-119","description":"Improper Restriction of Operations within the Bounds of a Memory Buffer","lang":"en","type":"CWE"}]}],"x_redhatCweChain":"CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer","timeline":[{"lang":"en","time":"2023-09-27T00:00:00.000Z","value":"Reported to Red Hat."},{"lang":"en","time":"2023-09-25T00:00:00.000Z","value":"Made public."}],"providerMetadata":{"orgId":"53f830b8-0a3f-465b-8143-3b8a9948e749","shortName":"redhat","dateUpdated":"2025-11-06T22:59:01.794Z"}},"adp":[{"title":"CVE Program Container","references":[{"url":"http://www.openwall.com/lists/oss-security/2023/12/13/3","tags":["x_transferred"]},{"url":"https://access.redhat.com/errata/RHSA-2023:7876","name":"RHSA-2023:7876","tags":["vendor-advisory","x_refsource_REDHAT","x_transferred"]},{"url":"https://access.redhat.com/errata/RHSA-2023:7879","name":"RHSA-2023:7879","tags":["vendor-advisory","x_refsource_REDHAT","x_transferred"]},{"url":"https://access.redhat.com/security/cve/CVE-2023-40661","tags":["vdb-entry","x_refsource_REDHAT","x_transferred"]},{"url":"https://bugzilla.redhat.com/show_bug.cgi?id=2240913","name":"RHBZ#2240913","tags":["issue-tracking","x_refsource_REDHAT","x_transferred"]},{"url":"https://github.com/OpenSC/OpenSC/issues/2792#issuecomment-1674806651","tags":["x_transferred"]},{"url":"https://github.com/OpenSC/OpenSC/releases/tag/0.24.0-rc1","tags":["x_transferred"]},{"url":"https://github.com/OpenSC/OpenSC/wiki/OpenSC-security-advisories","tags":["x_transferred"]},{"url":"https://lists.debian.org/debian-lts-announce/2023/11/msg00024.html","tags":["x_transferred"]},{"url":"https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/3CPQOMCDWFRBMEFR5VK4N5MMXXU42ODE/","tags":["x_transferred"]},{"url":"https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/GLYEFIBBA37TK3UNMZN5NOJ7IWCIXLQP/","tags":["x_transferred"]},{"url":"https://lists.debian.org/debian-lts-announce/2024/12/msg00026.html"}],"providerMetadata":{"orgId":"af854a3a-2127-422b-91ae-364da2661108","shortName":"CVE","dateUpdated":"2025-11-03T21:49:27.862Z"}}]}}
