2021-07-08Fix memory leak in i2d_ASN1_bio_streamOliver Mihatsch
When creating a signed S/MIME message using SMIME_write_CMS() if the reading from the bio fails, the state is therefore still ASN1_STATE_START when BIO_flush() is called by i2d_ASN1_bio_stream(). This results in calling asn1_bio_flush_ex cleanup but will only reset retry flags as the state is not ASN1_STATE_POST_COPY. Therefore 48 bytes (Linux x86_64) leaked since the ndef_prefix_free / ndef_suffix_free callbacks are not executed and the ndef_aux structure is not freed. By always calling free function callback in asn1_bio_free() the memory leak is fixed.

If an ASN1_OBJECT with such strings is passed to d2i_ASN1_OBJECT() for reuse, the strings must be freed, or there is a memory leak.

2021-03-21ASN1: Reset the content dump flag after dumpingRichard Levitte
When encountering a badly coded item, the DER printer (ASN1_print_dump()) sets a flag to ensure that an additional hex dump of the offending content is printed as part of the output. Unfortunately, this flag is never reset, which means that all following items are printed with the extra hex dump, whether they are faulty or not. Resetting the flag after hex dumping ensures that only the faulty contents are printed with the additional hex dump.

2019-09-27Reorganize local header filesDr. Matthias St. Pierre
Apart from public and internal header files, there is a third type called local header files, which are located next to source files in the source directory. Currently, they have different suffixes like '*_lcl.h', '*_local.h', or '*_int.h' This commit changes the different suffixes to '*_local.h' uniformly.

2019-09-27Reorganize private crypto header filesDr. Matthias St. Pierre
Currently, there are two different directories which contain internal header files of libcrypto which are meant to be shared internally: While header files in 'include/internal' are intended to be shared between libcrypto and libssl, the files in 'crypto/include/internal' are intended to be shared inside libcrypto only. To make things complicated, the include search path is set up in such a way that the directive #include "internal/file.h" could refer to a file in either of these two directoroes. This makes it necessary in some cases to add a '_int.h' suffix to some files to resolve this ambiguity: #include "internal/file.h" # located in 'include/internal' #include "internal/file_int.h" # located in 'crypto/include/internal' This commit moves the private crypto headers from 'crypto/include/internal' to 'include/crypto' As a result, the include directives become unambiguous #include "internal/file.h" # located in 'include/internal' #include "crypto/file.h" # located in 'include/crypto' hence the superfluous '_int.h' suffixes can be stripped. The files 'store_int.h' and 'store.h' need to be treated specially; they are joined into a single file.

2019-02-08Fix d2i_PublicKey() for EC keysTodd Short
o2i_ECPublicKey() requires an EC_KEY structure filled with an EC_GROUP. o2i_ECPublicKey() is called by d2i_PublicKey(). In order to fulfill the o2i_ECPublicKey()'s requirement, d2i_PublicKey() needs to be called with an EVP_PKEY with an EC_KEY containing an EC_GROUP. However, the call to EVP_PKEY_set_type() frees any existing key structure inside the EVP_PKEY, thus freeing the EC_KEY with the EC_GROUP that o2i_ECPublicKey() needs. This means you can't d2i_PublicKey() for an EC key... The fix is to check to see if the type is already set appropriately, and if so, not call EVP_PKEY_set_type().
