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, 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 CVE-2019-6290 and CVE-2019-6291.

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 of '{' characters. Remote attackers could leverage this vulnerability to cause a denial-of-service via a crafted asm file.

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 '+' or '-' characters. Remote attackers could leverage this vulnerability to cause a denial-of-service via a crafted asm file.

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

A Use After Free vulnerability in function new_Token in asm/preproc.c in nasm 2.14.02 allows attackers to cause a denial of service via crafted nasm command.

A stack-use-after-scope issue discovered in expand_mmac_params function in preproc.c in nasm before 2.15.04 allows remote attackers to cause a denial of service via crafted asm file.

Buffer overflow vulnerability in quote_for_pmake in asm/nasm.c in nasm before 2.15.05 allows attackers to cause a denial of service via crafted file.

NASM v2.16 was discovered to contain a heap buffer overflow in the component quote_for_pmake() asm/nasm.c:856
