CVE-2020-18974
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.
Publication Mise à jourCVE-2020-24978
In NASM 2.15.04rc3, there is a double-free vulnerability in pp_tokline asm/preproc.c. This is fixed in commit 8806c3ca007b84accac21dd88b900fb03614ceb7.
Publication Mise à jourCVE-2020-24242
In Netwide Assembler (NASM) 2.15rc10, SEGV can be triggered in tok_text in asm/preproc.c by accessing READ memory.
Publication Mise à jourCVE-2020-24241
In Netwide Assembler (NASM) 2.15rc10, there is heap use-after-free in saa_wbytes in nasmlib/saa.c.
Publication Mise à jourCVE-2019-20352
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.
Publication Mise à jourCVE-2019-20334
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.
Publication Mise à jourCVE-2019-14248
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.
Publication Mise à jourCVE-2019-8343
In Netwide Assembler (NASM) 2.14.02, there is a use-after-free in paste_tokens in asm/preproc.c.
Publication Mise à jourCVE-2019-7147
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.
Publication Mise à jourCVE-2019-6291
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.
Publication Mise à jourCVE-2019-6290
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.
Publication Mise à jourCVE-2018-20538
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.
Publication Mise à jourCVE-2018-20535
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.
Publication Mise à jourCVE-2018-1000886
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.
Publication Mise à jourCVE-2018-19755
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.
Publication Mise à jourCVE-2018-19215
Netwide Assembler (NASM) 2.14rc16 has a heap-based buffer over-read in expand_mmac_params in asm/preproc.c for the special cases of the % and $ and ! characters.
Publication Mise à jourCVE-2018-19214
Netwide Assembler (NASM) 2.14rc15 has a heap-based buffer over-read in expand_mmac_params in asm/preproc.c for insufficient input.
Publication Mise à jourCVE-2018-19213
Netwide Assembler (NASM) through 2.14rc16 has memory leaks that may lead to DoS, related to nasm_malloc in nasmlib/malloc.c.
Publication Mise à jourCVE-2018-19209
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.
