The OpenSSL public API function X509_issuer_and_serial_hash() attempts to create a unique hash value based on the issuer and serial number data contained within an X509 certificate. However it fails to correctly handle any errors that may occur while parsing the issuer field (which might occur if the issuer field is maliciously constructed). This may subsequently result in a NULL pointer deref and a crash leading to a potential denial of service attack. The function X509_issuer_and_serial_hash() is never directly called by OpenSSL itself so applications are only vulnerable if they use this function directly and they use it on certificates that may have been obtained from untrusted sources. OpenSSL versions 1.1.1i and below are affected by this issue. Users of these versions should upgrade to OpenSSL 1.1.1j. OpenSSL versions 1.0.2x and below are affected by this issue. However OpenSSL 1.0.2 is out of support and no longer receiving public updates. Premium support customers of OpenSSL 1.0.2 should upgrade to 1.0.2y. Other users should upgrade to 1.1.1j. Fixed in OpenSSL 1.1.1j (Affected 1.1.1-1.1.1i). Fixed in OpenSSL 1.0.2y (Affected 1.0.2-1.0.2x).
La función de la API pública de OpenSSL X509_issuer_and_serial_hash() intenta crear un valor hash único basado en los datos del emisor y del número de serie contenidos en un certificado X509. Sin embargo, no gestiona correctamente los errores que puedan producirse al analizar el campo del emisor (lo que podría ocurrir si el campo del emisor se construye de forma maliciosa). Esto puede dar lugar a un desvío de puntero NULL y a un fallo que conduzca a un posible ataque de denegación de servicio. La función X509_issuer_and_serial_hash() nunca es llamada directamente por OpenSSL, por lo que las aplicaciones sólo son vulnerables si utilizan esta función directamente y lo hacen con certificados que pueden haber sido obtenidos de fuentes no fiables. Las versiones de OpenSSL 1.1.1i y posteriores están afectadas por este problema. Los usuarios de estas versiones deberían actualizar a OpenSSL 1.1.1j. Las versiones de OpenSSL 1.0.2x e inferiores se ven afectadas por este problema. Sin embargo, OpenSSL 1.0.2 está fuera de soporte y ya no recibe actualizaciones públicas. Los clientes con soporte Premium de OpenSSL 1.0.2 deben actualizar a la versión 1.0.2y. Los demás usuarios deben actualizar a la versión 1.1.1j. Corregido en OpenSSL 1.1.1j (Afectado 1.1.1-1.1.1i). Corregido en OpenSSL 1.0.2y (Afectado 1.0.2-1.0.2x)
