About this tag
NASM, the Netwide Assembler, is a widely used assembler for x86/x86-64 development. Discussions on WindowsForum.com highlight several security vulnerabilities in NASM, including CVE-2022-46457, a segmentation fault in the IEEE output writer causing denial of service; CVE-2022-46456, a global buffer overflow in the debug output code; and CVE-2020-21528, a crash in the ieee_segment routine. These issues affect NASM version 2.16 and earlier, posing risks to build systems that process untrusted assembly input. Users are advised to apply patches and updates from upstream and distribution sources to mitigate these memory-safety and availability flaws.

    CVE-2022-46457: NASM IEEE Writer Segmentation Fault Causes DoS

    NASM users should immediately take notice: a segmentation fault bug in the IEEE output writer for NASM 2.16—tracked as CVE-2022-46457—can be triggered by a crafted assembly file and causes the assembler to crash, producing a denial-of-service condition for any workflow that processes untrusted...

    CVE-2022-46456: NASM Debug Output Buffer Overflow Analysis and Mitigations

    NASM users and maintainers should treat CVE‑2022‑46456 as a live, unresolved memory‑safety issue: Netwide Assembler (NASM) v2.16 contains a global buffer overflow in the dbg output code (function dbgdbg_typevalue in /output/outdbg.c) that can crash the assembler and, depending on circumstances...

    NASM CVE-2020-21528 DoS crash in ieee_segment and patch

    A segmentation fault in NASM’s ieee_segment routine quietly resurfaced as CVE‑2020‑21528: a small, narrowly scoped bug with outsized operational risk for build systems that accept untrusted assembly input. The flaw — rooted in outieee.c’s ieee_segment function — allowed a crafted assembly file...
