The incorrectly typed data is read only, used in a compare operation, so neither remote code execution, nor memory content disclosure were possible. However, applications performing certificate name checks were vulnerable to denial of service. The GENERAL_TYPE data type is a union, and we must take care to access the correct member, based on `gen->type`, not all the member fields have the same structure, and a segfault is possible if the wrong member field is read. The code in question was lightly refactored with the intent to make it more obviously correct.
