This security flaw cause a buffer overrun vulnerability in pkcs15 cardos_have_verifyrc_package. The attacker can supply a smart card package with malformed ASN1 context. The cardos_have_verifyrc_package function scans the ASN1 buffer for 2 tags, where remaining length is wrongly caculated due to moved starting pointer. This leads to possible heap-based buffer oob read. In cases where ASAN is enabled while compiling this causes a crash. Further info leak or more damage is possible."}], "lastModified": "2023-11-07T04:13:36.833", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:opensc_project:opensc:0.23.0:-:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "5359CB94-DE52-425E-AA8D-2792F953364F"}], "operator": "OR"}]}, {"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:o:redhat:enterprise_linux:8.0:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "F4CFF558-3C47-480D-A2F0-BABF26042943"}, {"criteria": "cpe:2.3:o:redhat:enterprise_linux:9.0:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "7F6FB57C-2BC7-487C-96DD-132683AEB35D"}], "operator": "OR"}]}], "sourceIdentifier": "secalert@redhat.com"}
