Summary
Issue summary: Processing a maliciously formatted PKCS12 file may lead OpenSSL to crash leading to a potential Denial of Service attack Impact summary: Applications loading files in the PKCS12 format from untrusted sources might terminate abruptly. A file in PKCS12 format can contain certificates and keys and may come from an untrusted source. The PKCS12 specification allows certain fields to be NULL, but OpenSSL does not correctly check for this case. This can lead to a NULL pointer dereference that results in OpenSSL crashing. If an application processes PKCS12 files from an untrusted source using the OpenSSL APIs then that application will be vulnerable to this issue. OpenSSL APIs that are vulnerable to this are: PKCS12_parse(), PKCS12_unpack_p7data(), PKCS12_unpack_p7encdata(), PKCS12_unpack_authsafes() and PKCS12_newpass(). We have also fixed a similar issue in SMIME_write_PKCS7(). However since this function is related to writing data we do not consider it security significant. The FIPS modules in 3.2, 3.1 and 3.0 are not affected by this issue.

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().
