The PKCS12 specification allows certain fields to be NULL, but\nOpenSSL does not correctly check for this case. This can lead to a NULL pointer\ndereference that results in OpenSSL crashing. If an application processes PKCS12\nfiles from an untrusted source using the OpenSSL APIs then that application will\nbe vulnerable to this issue.\n\nOpenSSL APIs that are vulnerable to this are: PKCS12_parse(),\nPKCS12_unpack_p7data(), PKCS12_unpack_p7encdata(), PKCS12_unpack_authsafes()\nand PKCS12_newpass().\n\nWe have also fixed a similar issue in SMIME_write_PKCS7(). However since this\nfunction is related to writing data we do not consider it security significant.\n\nThe FIPS modules in 3.2, 3.1 and 3.0 are not affected by this issue."}, {"lang": "es", "value": "Resumen del problema: el procesamiento de un archivo PKCS12 con formato malintencionado puede hacer que OpenSSL falle y provoque un posible ataque de denegaci\u00f3n de servicio. Resumen de impacto: las aplicaciones que cargan archivos en formato PKCS12 desde fuentes que no son de confianza pueden finalizar abruptamente. Un archivo en formato PKCS12 puede contener certificados y claves y puede provenir de una fuente que no es de confianza. La especificaci\u00f3n PKCS12 permite que ciertos campos sean NULL, pero OpenSSL no verifica correctamente este caso. Esto puede provocar una desreferencia del puntero NULL que provoque el bloqueo de OpenSSL. Si una aplicaci\u00f3n procesa archivos PKCS12 de una fuente que no es de confianza utilizando las API de OpenSSL, esa aplicaci\u00f3n ser\u00e1 vulnerable a este problema. Las API de OpenSSL que son vulnerables a esto son: PKCS12_parse(), PKCS12_unpack_p7data(), PKCS12_unpack_p7encdata(), PKCS12_unpack_authsafes() y PKCS12_newpass(). Tambi\u00e9n solucionamos un problema similar en SMIME_write_PKCS7(). Sin embargo, dado que esta funci\u00f3n est\u00e1 relacionada con la escritura de datos, no la consideramos importante para la seguridad. Los m\u00f3dulos FIPS en 3.2, 3.1 y 3.0 no se ven afectados por este problema."}], "lastModified": "2024-02-08T10:15:13.910", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:openssl:openssl:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "E30B9424-68AA-4ED4-A1CB-3DA32A2350EC", "versionEndExcluding": "1.0.2zj", "versionStartIncluding": "1.0.2"}, {"criteria": "cpe:2.3:a:openssl:openssl:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "93CF937D-2520-44AF-B40B-B41720BEAB36", "versionEndExcluding": "1.1.1x", "versionStartIncluding": "1.1.1"}, {"criteria": "cpe:2.3:a:openssl:openssl:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "21346C7C-ED3A-43D4-BBCB-41D62F7ACBF2", "versionEndExcluding": "3.0.13", "versionStartIncluding": "3.0.0"}, {"criteria": "cpe:2.3:a:openssl:openssl:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "AAD34F57-90D2-415F-9544-70B594D04E53", "versionEndExcluding": "3.1.5", "versionStartIncluding": "3.1.0"}, {"criteria": "cpe:2.3:a:openssl:openssl:3.2.0:-:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "AA5220D8-3CAD-4524-BA73-1656FB437446"}], "operator": "OR"}]}], "sourceIdentifier": "openssl-security@openssl.org"}
