Vulnerabilities for 'Netwide assembler'

2021-08-25

CVE-2020-18974

CWE-120

Buffer Overflow in Netwide Assembler (NASM) v2.15.xx allows attackers to cause a denial of service via 'crc64i' in the component 'nasmlib/crc64'. This issue is different than CVE-2019-7147.

CVE-2020-24242

NVD-CWE-noinfo

In Netwide Assembler (NASM) 2.15rc10, SEGV can be triggered in tok_text in asm/preproc.c by accessing READ memory.

CVE-2020-24241

CWE-416

In Netwide Assembler (NASM) 2.15rc10, there is heap use-after-free in saa_wbytes in nasmlib/saa.c.

2020-01-06

CVE-2019-20352

CWE-125

In Netwide Assembler (NASM) 2.15rc0, a heap-based buffer over-read occurs (via a crafted .asm file) in set_text_free when called from expand_one_smacro in asm/preproc.c.

2020-01-04

CVE-2019-20334

CWE-400

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.

2019-07-24

CVE-2019-14248

CWE-476

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.

2019-02-15

CVE-2019-8343

CWE-416

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

2019-01-28

CVE-2019-7147

CWE-119

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.

2019-01-14

CVE-2019-6291

CWE-400

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.

CVE-2019-6290

CWE-400

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.
