|
* Add EVP_CIPHER_meth_* documentation from OpenSSL 1.1tb2023-03-161-0/+335
| | | | | | | | This is essentially the original text with a few tweaks and fixes by me, removing parts inapplicable to LibreSSL. There are dangling references to EVP_CIPHER_CTX_copy(3) and EVP_CIPHER_CTX_get_cipher_data(3). This all isn't great, but it's better than nothing. Probably good enough for these rarely used functions.

* Return the signature length after successful signing operationtb2023-03-151-1/+3
| | | | | | | | | This is required behavior of the EVP_DigestSign() API, but seemingly almost nothing uses this. Well, turns out ldns does. Reported by Stephane. Helpful comments by sthen. ok jsing

| | | | | | There's some method to this madness. ok jsing

* Streaming BIOs assume they can write to NULL BIOstb2023-03-151-5/+4
| | | | | | | | | | At least SMIME_text() relies on this. Pushing an error on the stack trips PKCS7 regress in py-cryptography, so indicate nothing was written instead of throwing an error. Reported by Alex Gaynor a while back ok jsing
* Ensure negative input to BN_mod_exp_mont_consttime() is correctly reduced.jsing2023-03-151-7/+4
| | | | | | | | | | A negative input to BN_mod_exp_mont_consttime() is not correctly reduced, remaining negative (when it should be in the range [0, m)). Fix this by unconditionally calling BN_nnmod() on the input. Fixes ossfuzz #55997. ok tb@
* Include tests with negative values in BN_mod_exp* regress.jsing2023-03-151-2/+15
| | | | This currently fails.

* Stop confusing out and asn_bio in BIO_new_NDEF()tb2023-03-131-4/+4
| | | | | | | | | | BIO_new_NDEF() sets up an ASN.1 BIO to the output chain and then adds even more BIOs. Since BIO_push(bio, new_tail) returns bio on success, after the if ((out = BIO_push(asn_bio, out)) != NULL) the 'out' BIO and the 'asn_bio' are the same. The code then goes on and uses one or the other. This is very confusing. Simply stop using out once it's appended to asn_bio. ok jsing
* pk7_cb() and cms_cb()tb2023-03-122-5/+8
| | | | | | Add and fix FALLTHROUGH statement. I was confused for way too long since I hadn't noticed that this case fell through to the next. Also add and move some empty lines in the cms_cb() to make this resemble KNF more.
* Avoid an 1 byte out-of-bounds read in ASN1_PRINTABLE_type()tb2023-03-121-2/+2
| | | | | | | | | | | In case the input is not NUL terminated, the reversed check for length and terminating NUL results in a one-byte overread. The documentation says that the input should be a string, but in ASN.1 land you never know... Reported by Guido Vranken a while back ok beck

* Tiny cleanup for readabilitytb2023-03-111-4/+5
| | | | | Turn a malloc() into calloc() and check two function calls directly forever instead of a combined check afterward.
* Use "if (ptr == NULL)" instead of "if (!ptr)"tb2023-03-111-3/+3
| | | | Requested by jsing
* Fix double free after BIO_new_NDEF()tb2023-03-111-6/+7
| | | | | | | | | | | | Once the asn_bio is prepended to the out chain, and before the asn1_cb() has done its thing, asn_bio needs to be popped off again on error. Failing to do this can cause write after frees or double frees when the out BIO is used after the function returned. Based on a very complicated diff by Matt Caswell and Viktor Dukhovni. This was part of the fixes in OpenSSL 1.1.1t. ok jsing
* Fix an off-by-one in dsa_check_key()tb2023-03-111-2/+2
| | | | | | | | | | The private key is a random number in [1, q-1], so 1 must be allowed. Since q is at least an 160-bit prime and 2^159 + 1 is not prime (159 is not a power of 2), the probability that this is hit is < 2^-159, but a tiny little bit wrong is still wrong. Found while investigating a report by bluhm ok jsing

| | | | This gets us some minimal test coverage.
* Avoid -0 in BN_div_word().jsing2023-03-111-1/+5
| | | | | | | | | Currently, the use of BN_div_word() can result in -0 - avoid this by setting negative again, at the end of the computation. Should fix oss-fuzz 56667. ok tb@
* Correct sign handling in BN_add_word().jsing2023-03-111-3/+3
| | | | | | | | | | | | A sign handling bug was introduced to BN_add_word() in bn_word.c r1.18. When handling addition to a negative bignum, the BN_sub_word() call can result in the sign being flipped, which we need to account for. Use the same code in BN_sub_word() - while not technically needed here it keeps the code consistent. Issue discovered by tb@ ok tb@

| | | | | | | This also provides some indirect coverage for BN_hex2bn(), BN_bn2hex() and BN_get_word(). Two of these tests are currently failing and will be fixed shortly.

* ASN.1 BIO: properly wire up prefix_free and suffix_freetb2023-03-101-1/+7
| | | | | | | | | | | | | | If something goes wrong before the ASN.1 BIO state machine has passed both flushing states, asn1_bio_free() forgets to free the ndef_aux and the ex_arg since the prefix_free() and suffix_free callbacks are not called. This can lead to leaks, notably in streaming bios. Part of https://github.com/openssl/openssl/pull/15999 I have a regress covering this but it is not yet ready to land. ok beck jsing
* Return the correct type for ASN.1 BOOLEANstb2023-03-101-5/+9
| | | | | | | | | | | | | ASN.1 BOOLEANs and ASN.1 NULL are handled specially in the ASN.1 sausage factory and they are special in that they don't have a->value.ptr set. Both need to be special cased here since they fail the a->type.ptr != NULL check. Apart from fixing an obvious bug in ASN1_TYPE_get(), this fixes another crash in openssl(1) asn1parse. There is more to do in the vicinity, but that is more complex and will have to wait for OpenBSD 7.3-current. with/ok jsing
* openssl(1) asn1parse: avoid crash with ASN.1 BOOLEANStb2023-03-101-3/+4
| | | | | | | | | | | | | When pointing openssl asn1parse -strparse at DER octets 01 01, it crashes: $ printf '<\x01\x01>' | openssl asn1parse -inform der -strparse 1 Refuse to parse BOOLEAN types instead, which avoids a crash in hensonian /* hmm... this is a little evil, but it works */ code.
