Nasm Netwide Assembler: vulnerabilidades y CVE

NASM’s disasm() function contains a stack based buffer overflow when formatting disassembly output, allowing an attacker triggered out-of-bounds write when `slen` exceeds the buffer capacity.

NASM contains a heap use after free vulnerability in response file (-@) processing where a dangling pointer to freed memory is stored in the global depend_file and later dereferenced, as the response-file buffer is…

A heap buffer overflow vulnerability exists in the Netwide Assembler (NASM) due to a lack of bounds checking in the obj_directive() function. This vulnerability can be exploited by a user assembling a malicious .asm…

A vulnerability has been found in NASM Netwide Assember 2.17rc0. Affected is the function parse_line of the file parser.c. The manipulation leads to stack-based buffer overflow. The attack needs to be approached…

A vulnerability was identified in NASM Netwide Assember 2.17rc0. This issue affects the function assemble_file of the file nasm.c. The manipulation leads to stack-based buffer overflow. It is possible to launch the…

A vulnerability was determined in NASM Netwide Assember 2.17rc0. This vulnerability affects the function parse_smacro_template of the file preproc.c. The manipulation leads to null pointer dereference. Attacking locally…

A vulnerability was found in NASM Netwide Assember 2.17rc0. This affects the function macho_no_dead_strip of the file outmacho.c. The manipulation leads to heap-based buffer overflow. Local access is required to…

A vulnerability has been found in NASM Netwide Assember 2.17rc0. Affected by this issue is the function do_directive of the file preproc.c. The manipulation leads to use after free. An attack has to be approached…
