When a token/card is authenticated by one process, it can perform cryptographic operations in other processes when an empty zero-length pin is passed. This issue poses a security risk, particularly for OS logon/screen unlock and for small, permanently connected tokens to computers. Additionally, the token can internally track login status. This flaw allows an attacker to gain unauthorized access, carry out malicious actions, or compromise the system without the user's awareness." } ], "affected": [ { "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-2023-40660", "tags": [ "vdb-entry", "x_refsource_REDHAT" ] }, { "url": "https://bugzilla.redhat.com/show_bug.cgi?id=2240912", "name": "RHBZ#2240912", "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+00:00", "problemTypes": [ { "descriptions": [ { "cweId": "CWE-287", "description": "Improper Authentication", "lang": "en", "type": "CWE" } ] } ], "x_redhatCweChain": "CWE-287: Improper Authentication", "timeline": [ { "lang": "en", "time": "2023-09-27T00:00:00+00:00", "value": "Reported to Red Hat." }, { "lang": "en", "time": "2023-09-25T00:00:00+00:00", "value": "Made public." } ], "credits": [ { "lang": "en", "value": "Upstream acknowledges Deepanjan Pal (Oracle Corporation) as the original reporter." } ], "providerMetadata": { "orgId": "53f830b8-0a3f-465b-8143-3b8a9948e749", "shortName": "redhat", "dateUpdated": "2024-09-16T16:10:49.374Z" } }, "adp": [ { "providerMetadata": { "orgId": "af854a3a-2127-422b-91ae-364da2661108", "shortName": "CVE", "dateUpdated": "2024-08-02T18:38:51.123Z" }, "title": "CVE Program Container", "references": [ { "url": "http://www.openwall.com/lists/oss-security/2023/12/13/2", "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-2023-40660", "tags": [ "vdb-entry", "x_refsource_REDHAT", "x_transferred" ] }, { "url": "https://bugzilla.redhat.com/show_bug.cgi?id=2240912", "name": "RHBZ#2240912", "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" ] } ] } ] } }
