4Subject: [PATCH] Check for errors in BN_bn2dec()
5
6If an oversize BIGNUM is presented to BN_bn2dec() it can cause
7BN_div_word() to fail and not reduce the value of 't' resulting
8in OOB writes to the bn_data buffer and eventually crashing.
9
10Fix by checking return value of BN_div_word() and checking writes
11don't overflow buffer.
