* Allocate md_data with calloc to avoid use of uninitialised memory.jsing2019-04-191-6/+6

* Remove two pointless chunks of code.jsing2019-04-141-16/+1
| | | | | | | | This reverts part of OpenSSL c2fd5d79, which added the same code to AES CCM, GCM and XTS. In the case of CCM and GCM nothing assigns {ccm,gcm}.key so there is never going to be anything to update (unlike XTS). ok tb@

* Avoid potential double-frees following EVP_CIPHER_CTX_copy().jsing2019-04-141-4/+17
| | | | | | | | | | | In the case of a cipher with a custom copy control, if that control fails we may still have pointers that we do not own in the previously copied cipher data. Avoid potential double-frees by zeroing and freeing the copied cipher data in this case. Issue reported by Guido Vranken. ok tb@
* Avoid some out of bound accesses in aesni_cbc_hmac_sha1_cipher().tb2019-04-031-7/+13
| | | | | | | | | | | | | | | The plen variable can be NO_PAYLOAD_LENGTH == (size_t)-1, so doing tls_aad[plen-4] is no good. Also check that the length of the AAD set via the control interface is equal to 13 since the whole file is written with that case in mind. Note that we no longer use this code in LibreSSL/OpenBSD. We eliminated the use of these control interfaces and stitched cipher modes in libssl a while ago. Problem found by Guido Vranken with his cryptofuzz - thanks! input & ok beck, jsing

| | | | | | | | | Requires adding a const to the priv_decode() member of EVP_PKEY_ASN1_METHOD and adjusting all *_priv_decode() functions. All this is already documented this way. tested in a bulk build by sthen ok jsing

| | | | | | | | we can add const to PKCS8_pkey_get0(). In order for this to work, we need to sprinkle a few consts here and there. tested in a bulk by sthen ok jsing

| | | | | | | | | | | Provide PKCS8_pkey_add1_attr_by_NID() and PKCS8_pkey_get0_attrs(). Remove the whole broken code and simplify pkcs8_priv_key_info_st accordingly. Based on OpenSSL commit 54dbf42398e23349b59f258a3dd60387bbc5ba13 plus some const that was added later. tested in a bulk build by sthen ok jsing

* The UI_add_{input,verify}_string() functions want a length not includingtb2018-08-141-5/+8
| | | | | | | | | | | | | | the terminating NUL. EVP_read_pw_string_min() got this wrong, leading to a one-byte buffer overrun in all callers of EVP_read_pw_string(). Found by mestre running 'openssl passwd' with MALLOC_OPTIONS including C. Fix this by doing some basic sanity checking in EVP_read_pw_string_min(). Cap the len argument at BUFSIZ and ensure that min < len as well as 0 <= min and 1 <= len. The last two checks are important as these numbers may end up in reallocarray(). ok bcook (on previous version), jsing, mestre

| | | | | | | | | | | OpenSSL commit 7c96dbcdab9 by Rich Salz. This cleans up the caller side quite a bit and reduces the number of lines enclosed in #ifndef OPENSSL_NO_ENGINE. codesearch.debian.net shows that almost nothing checks the return value of ENGINE_finish(). While there, replace a few nearby 'if (!ptr)' with 'if (ptr == NULL)'. ok jsing, tested by & ok inoguchi
