NASM Netwide Assembler 2.14.0

asm/labels.c in Netwide Assembler (NASM) is prone to NULL Pointer Dereference, which allows the attacker to cause a denial of service via a crafted file.

NASM nasm-2.13.03 nasm- 2.14rc15 version 2.14rc15 and earlier contains a memory corruption (crashed) of nasm when handling a crafted file due to function assemble_file(inname, depend_ptr) at asm/nasm.c:482. vulnerability in function assemble_file(inname, depend_ptr) at asm/nasm.c:482. that can result in aborting/crash nasm program. This attack appear to be exploitable via a specially crafted asm file..

There is a use-after-free at asm/preproc.c (function pp_getline) in Netwide Assembler (NASM) 2.14rc16 that will cause a denial of service during a line-number increment attempt.

There is a use-after-free at asm/preproc.c (function pp_getline) in Netwide Assembler (NASM) 2.14rc16 that will cause a denial of service during certain finishes tests.

Netwide Assembler (NASM) 2.14rc15 has a NULL pointer dereference in the function find_label in asm/labels.c that will lead to a DoS attack.
