* Fix a memory leak in the error path in ASN1_mbstring_ncopy().miod2014-09-211-19/+29
| | | | | | | Replace an if() posse with a switch() statement in traverse_string(). Remove unnecessary casts in cpy_*(), with tweaks from guenther@; ok bcook@ jsing@ guenther@
* Fix CVE-2014-3508, pretty printing and OID validation:guenther2014-08-081-10/+21
| | | | | | | | | | | - make sure the output buffer is always NUL terminated if buf_len was initially greater than zero. - reject OIDs that are too long, too short, or not in proper base-127 Based on https://git.openssl.org/gitweb/?p=openssl.git;a=commit;h=0042fb5fd1c9d257d713b15a1f45da05cf5c1c87 ok bcook@

* A few fixes/improvements:miod2014-07-121-20/+19
| | | | | | | | | | | | | | | | - first, BN_free == BN_clear_free in our libcrypto, so we do not need to treat CBIGNUM (crypto BN) separately from BIGNUM (regular BN). - then, in bn_i2c(), since BN_bn2bin returns BN_num_bytes(input), take advantage of this to avoid calling BN_num_bytes() a second time. BN_num_bytes() is cheap, but this not a reason to perform redundant work. - finally, in bn_c2i, if bn_new() fails, return early. Otherwise BN_bin2bn will try to create a BN too, and although this will probably fail since we were already out of memory, if we are on a threaded process and suddenly the allocation succeeds, we will leak it since it will never be stored in *pval. ok jsing@

This avoids relying on something else pulling it in for us, plus it fixes several cases where the #ifndef OPENSSL_NO_XYZ is never going to do anything, since OPENSSL_NO_XYZ will never defined, due to the fact that opensslconf.h has not been included. This also includes some miscellaneous sorting/tidying of headers.
