Nasm ≫ Netwide Assembler

In Netwide Assembler (NASM) 2.14.02, stack consumption occurs in expr# functions in asm/eval.c. This potentially affects the relationships among expr0, expr1, expr2, expr3, expr4, expr5, and expr6 (and stdscan in asm/stdscan.c). This is similar to CV...

In libnasm.a in Netwide Assembler (NASM) 2.14.xx, asm/pragma.c allows a NULL pointer dereference in process_pragma, search_pragma_list, and nasm_set_limit when "%pragma limit" is mishandled.

In Netwide Assembler (NASM) 2.14.02, there is a use-after-free in paste_tokens in asm/preproc.c.

A buffer over-read exists in the function crc64ib in crc64.c in nasmlib in Netwide Assembler (NASM) 2.14rc16. A crafted asm input can cause segmentation faults, leading to denial-of-service.

An issue was discovered in the function expr6 in eval.c in Netwide Assembler (NASM) through 2.14.02. There is a stack exhaustion problem caused by the expr6 function making recursive calls to itself in certain scenarios involving lots of '!' or '+' o...

An infinite recursion issue was discovered in eval.c in Netwide Assembler (NASM) through 2.14.02. There is a stack exhaustion problem resulting from infinite recursion in the functions expr, rexp, bexpr and cexpr in certain scenarios involving lots o...

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.

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.

nasm version 2.14.01rc5, 2.15 contains a Buffer Overflow vulnerability in asm/stdscan.c:130 that can result in Stack-overflow caused by triggering endless macro generation, crash the program. This attack appear to be exploitable via a crafted nasm in...

There is an illegal address access at asm/preproc.c (function: is_mmacro) in Netwide Assembler (NASM) 2.14rc16 that will cause a denial of service (out-of-bounds array access) because a certain conversion can result in a negative integer.
