In Netwide Assembler (NASM) 2.14rc0, there are multiple heap use after free
vulnerabilities in the tool nasm. The related heap is allocated in the
token() function and freed in the detoken() function (called by
pp_getline()) - it is used again at multiple positions later that could
cause multiple damages. For example, it causes a corrupted double-linked
list in detoken(), a double free or corruption in delete_Token(), and an
out-of-bounds write in detoken(). It has a high possibility to lead to a
remote code execution attack.
