* Fix a NULL dereference in GENERAL_NAME_cmp()libressl-v3.1.5OPENBSD_6_7tb2020-12-085-5/+48
| | | | | | | | | | | | | | Comparing two GENERAL_NAME structures containing an EDIPARTYNAME can lead to a crash. This enables a denial of service attack for an attacker who can control both sides of the comparison. Issue reported to OpenSSL on Nov 9 by David Benjamin. OpenSSL shared the information with us on Dec 1st. Fix from Matt Caswell (OpenSSL) with a few small tweaks. ok jsing this is errata/6.7/031_asn1.patch.sig

* Fix ASN1 print functionsinoguchi2020-03-241-6/+13
| | | | | | | | | | | | Check and print out boolean type properly. Based on OpenSSL commit ad72d9fdf7709ddb97a58d7d45d755e6e0504b96. Reduced unneeded parentheses from if condition. Check return value from i2s_ASN1_INTEGER. Based on OpenSSL commit 5e3553c2de9a365479324b8ba8b998f0cce3e527. Added if condition expression and return 0 if NULL is returned. ok tb@

* Avoid an overread caused by d2i_PrivateKey().jsing2019-04-101-1/+3
| | | | | | | | | | | There are cases where the old_priv_decode() function can fail but consume bytes. This will result in the pp pointer being advanced, which causes d2i_PKCS8_PRIV_KEY_INFO() to be called with an advanced pointer and incorrect length. Fixes oss-fuzz #13803 and #14142. ok deraadt@ tb@
* Revert tasn_prn.c r1.18.jsing2019-04-071-6/+2
| | | | | | | | | | | In this code, just because something is cast to a type doesn't mean it is necessarily that type - in this case we cannot check the length of the ASN1_STRING here, since it might be another data type and later handled as an int (for example, in the V_ASN1_BOOLEAN case). We will revisit this post release. ok tb@

* Require all ASN1_PRIMITIVE_FUNCS functions to be provided.jsing2019-04-015-26/+42
| | | | | | | | | | | | If an ASN.1 item provides its own ASN1_PRIMITIVE_FUNCS functions, require all functions to be provided (currently excluding prim_clear). This avoids situations such as having a custom allocator that returns a specific struct but then is then printed using the default primative print functions, which interpret the memory as a different struct.

* Fix a number of ASN1_INTEGER vs ASN1_STRING mixups coming from thetb2019-03-131-4/+2
| | | | | | | | | | | mechanical M_ASN1 macro expansion. The ASN1_INTEGER_cmp function takes signs into account while ASN1_STRING_cmp doesn't. The mixups mostly involve serialNumbers, which, in principle, should be positive. However, it is unclear whether that is checked or enforced anywhere in the code, so these are probably bugs.
