The sh_add_to_list function will overwrite subsequent slots in the free list for small allocations. This causes a segmentation fault if the writes goes off the end of the secure memory. I've not investigated if this problem can overwrite memory without the segmentation fault, but it seems likely. This fix limits the minsize to the sizeof of the SH_LIST structure (which also has a side effect of properly aligning the pointers). The alternative would be to return an error if minsize is too small. Reviewed-by:

Prevent undefined behavior in CRYPTO_cbc128_encrypt: calling this function with the 'len' parameter being 0 would result in a memcpy where the source and destination parameters are the same, which is undefined behavior. Do same for AES_ige_encrypt. Reviewed-by:

On VMS, file names with more than one period get all but the last get escaped with a ^, so 21-key-update.conf.in becomes 21-key-update^.conf.in That means that %conf_dependent_tests and %skip become useless unless we massage the file names that are used as indexes. Reviewed-by:

The intent seems to be that the WIN32 symbol is for things that are a direct byproduct of being a windows-variant configuration and should be used for feature en/disablement on windows systems. Use of the _WIN32 symbol is more widespread, being used to implement platform portability of more generic code. We do define WIN32 in some situations in e_os.h, but that is not included universally.

Following on from CVE-2017-3733, this removes the OPENSSL_assert() check that failed and replaces it with a soft assert, and an explicit check of value with an error return if it fails. Reviewed-by: -

Changing the ciphersuite during a renegotiation can result in a crash leading to a DoS attack. ETM has not been implemented in 1.1.0 for DTLS so this is TLS only. The problem is caused by changing the flag indicating whether to use ETM or not immediately on negotiation of ETM, rather than at CCS. Therefore, during a renegotiation, if the ETM state is changing (usually due to a change of ciphersuite), then an error/crash will occur. Due to the fact that there are separate CCS messages for read and write we actually now need two flags to determine whether to use ETM or not. CVE-2017-3733 Reviewed-by: -

which are not possible with the default OPENSSL_zalloc, but are possible if the user has installed their own allocator using CRYPTO_set_mem_functions. If the 0-allocations succeeds, the secure heap code will later access (at least) the first byte of that space, which is technically an OOB access. This could lead to problems with some custom allocators that only return a valid pointer for subsequent free()-ing, and do not expect that the pointer is actually dereferenced. Reviewed-by:

While it's always safe to read |SSL_MAX_SSL_SESSION_ID_LENGTH| bytes from an |SSL_SESSION|'s |session_id| array, the hash function would do so with without considering if all those bytes had been written to. This change checks |session_id_length| before possibly reading uninitialised memory. Since the result of the hash function was already attacker controlled, and since a lookup of a short session ID will always fail, it doesn't appear that this is anything more than a clean up. In particular, |ssl_get_prev_session| uses a stack-allocated placeholder |SSL_SESSION| as a lookup key, so the |session_id| array may be uninitialised. This was originally found with libFuzzer and MSan in https://boringssl.googlesource.com/boringssl/+/e976e4349d693b4bbb97e1694f45be5a1b22c8c7 , then by Robert Swiecki with honggfuzz and MSan here. Thanks to both. Reviewed-by:
