2024-05-06Fix error handling in CMS_EncryptedData_encryptBernd Edlinger
That caused several memory leaks in case of error. Also when the CMS object that is created by CMS_EncryptedData_encrypt is not used in the normal way, but instead just deleted by CMS_ContentInfo_free some memory was lost.

2024-01-25Add appropriate NULL checks in EVP_CIPHER apiNeil Horman
The EVP_CIPHER api currently assumes that calls made into several APIs have already initalized the cipher in a given context via a call to EVP_CipherInit[_ex[2]]. If that hasnt been done, instead of an error, the result is typically a SIGSEGV.

2023-10-30free oaep label-octet-string on errorJames Muir
When successful, ossl_X509_ALGOR_from_nid() returns a pointer to an X509_ALGOR object. Inside ossl_X509_ALGOR_from_nid(), X509_ALGOR_set0() is called, and this passes ownership of the ASN1 object "los" (label octet string) to the X509_ALGOR object. When ossl_X509_ALGOR_from_nid() fails, ownership has not been passed on and we need to free "los". Change the scope of "los" and ensure it is freed on failure (on success, set it to NULL so it is not freed inside the function).

Fixes #19975 for CMS_decrypt_set1_pkey_and_peer() in the obvious way, and a related potential crash in CMS_decrypt_set1_password(). The point is that the input might have an unexpected content type, so a guard is needed at both places after `ec` is obtained. Note that in CMS_decrypt_set1_pkey_and_peer() there was no such ec != NULL guard for ``` if (ris != NULL) debug = ec->debug; ``` maybe because it is implied here by ris != NULL.

2022-12-08Obtain PSS salt length from providerClemens Lang
Rather than computing the PSS salt length again in core using ossl_rsa_ctx_to_pss_string, which calls rsa_ctx_to_pss and computes the salt length, obtain it from the provider using the OSSL_SIGNATURE_PARAM_ALGORITHM_ID param to handle the case where the interpretation of the magic constants in the provider differs from that of OpenSSL core. Add tests that verify that the rsa_pss_saltlen:max, rsa_pss_saltlen:<integer> and rsa_pss_saltlen:digest options work and put the computed digest length into the CMS_ContentInfo struct when using CMS. Do not add a test for the salt length generated by a provider when no specific rsa_pss_saltlen option is defined, since that number could change between providers and provider versions, and we want to preserve compatibility with older providers.

2022-10-05Stop raising ERR_R_MALLOC_FAILURE in most placesRichard Levitte
Since OPENSSL_malloc() and friends report ERR_R_MALLOC_FAILURE, and at least handle the file name and line number they are called from, there's no need to report ERR_R_MALLOC_FAILURE where they are called directly, or when SSLfatal() and RLAYERfatal() is used, the reason `ERR_R_MALLOC_FAILURE` is changed to `ERR_R_CRYPTO_LIB`. There were a number of places where `ERR_R_MALLOC_FAILURE` was reported even though it was a function from a different sub-system that was called. Those places are changed to report ERR_R_{lib}_LIB, where {lib} is the name of that sub-system. Some of them are tricky to get right, as we have a lot of functions that belong in the ASN1 sub-system, and all the `sk_` calls or from the CRYPTO sub-system. Some extra adaptation was necessary where there were custom OPENSSL_malloc() wrappers, and some bugs are fixed alongside these changes.
