Buffer overflow in the listing module in Netwide Assembler (NASM) before 2.03.01 has unknown impact and attack vectors, a different vulnerability than CVE-2008-2719.
In Netwide Assembler (NASM) 2.14rc0, preproc.c allows remote attackers to cause a denial of service (heap-based buffer overflow and application crash) or possibly have unspecified other impact via a crafted file.
Netwide Assembler (NASM) 2.13 has a stack-based buffer over-read in the disasm function of the disasm/disasm.c file. Remote attackers could leverage this vulnerability to cause a denial of service or possibly have unspecified other impact via a crafted ELF file.
NASM v2.16 was discovered to contain a heap buffer overflow in the component quoteforpmake() asm/nasm.c:856
There exists a heap buffer overflow in nasm 2.16.02rc1 (GitHub commit: b952891).
In Netwide Assembler (NASM) 2.15rc0, a heap-based buffer over-read occurs (via a crafted .asm file) in settextfree when called from expandonesmacro in asm/preproc.c.
Off-by-one error in the ppscan function (preproc.c) in Netwide Assembler (NASM) 2.02 allows context-dependent attackers to cause a denial of service (crash) and possibly execute arbitrary code via a crafted file that triggers a stack-based buffer overflow.
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 assemblefile(inname, dependptr) at asm/nasm.c:482. vulnerability in function assemblefile(inname, dependptr) 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..
Netwide Assembler (NASM) 2.14rc15 has a buffer over-read in x86/regflags.c.
In Netwide Assembler (NASM) 2.14rc0, there is an illegal address access in the function pastetokens() in preproc.c, aka a NULL pointer dereference. It will lead to remote denial of service.
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.
Netwide Assembler (NASM) through 2.14rc16 has memory leaks that may lead to DoS, related to nasmmalloc in nasmlib/malloc.c.
There is a use-after-free at asm/preproc.c (function ppgetline) 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 ppgetline) in Netwide Assembler (NASM) 2.14rc16 that will cause a denial of service during certain finishes tests.
There is an illegal address access at asm/preproc.c (function: ismmacro) 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.
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 loop vulnerability exists in nasm 2.16rc0 via the gpastetokens function.
A Null Pointer Dereference vulnerability existfs in nasm 2.16rc0 via asm/preproc.c.
Netwide Assembler (NASM) 2.14rc15 has an invalid memory write (segmentation fault) in expandsmacro in preproc.c, which allows attackers to cause a denial of service via a crafted input file.
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.
In Netwide Assembler (NASM) 2.15rc10, there is heap use-after-free in saawbytes in nasmlib/saa.c.
In Netwide Assembler (NASM) 2.15rc10, SEGV can be triggered in toktext in asm/preproc.c by accessing READ memory.
In libnasm.a in Netwide Assembler (NASM) 2.14.xx, asm/pragma.c allows a NULL pointer dereference in processpragma, searchpragmalist, and nasmsetlimit when "%pragma limit" is mishandled.
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.
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 input file.
Netwide Assembler (NASM) 2.14rc0 has an endless while loop in the assemblefile function of asm/nasm.c because of a globallineno integer overflow.
Netwide Assembler (NASM) 2.14rc0 has a division-by-zero vulnerability in the expr5 function in asm/eval.c via a malformed input file.
NASM 2.16 (development) is vulnerable to 476: Null Pointer Dereference via output/outaout.c.
NASM v2.16 was discovered to contain a null pointer deference in the NASM component
