About this tag
YASM is an open-source x86/x86-64 assembler used as a drop-in alternative to NASM in many build systems and developer toolchains. Discussions on WindowsForum highlight security vulnerabilities in YASM, including CVE-2023-51258, a memory leak in the NASM preprocessor's new_Token routine that can be exploited locally to exhaust memory, and CVE-2024-22653, a NULL-pointer dereference with supply-chain implications for Microsoft-maintained Linux images. The tag also covers YASM's role in assembly programming, such as in FFmpeg's hand-written SIMD code for high-performance media pipelines. Topics include patching strategies, build host updates, and the importance of validating upstream commits for security fixes.

    CVE-2023-51258: Local memory leak in YASM preprocessor new_Token (1.3.0)

    A small, targeted memory leak in the YASM assembler has emerged as a quietly dangerous availability problem: CVE-2023-51258 identifies a leak in the new_Token routine of the NASM preprocessor module that can be triggered by local users and, when exploited repeatedly, can exhaust memory and deny...

    CVE-2024-22653: Yasm Patch and Microsoft Supply Chain Impact

    A NULL-pointer dereference discovered in the Yasm assembler (tracked as CVE-2024-22653) is small in code but broad in consequence: the bug lived in a widely reused open-source component, was fixed in a targeted upstream commit, and — contrary to a narrow reading of a Microsoft FAQ — the presence...

    FFmpeg Assembly Lessons: Hand-Written SIMD for High-Performance Media

    FFmpeg’s new assembly lessons have turned a niche skill into a teachable path: a compact, practical curriculum aimed squarely at developers who want to write the kind of hand-optimized SIMD code that still powers the highest-performance media pipelines. The lessons, published as a public...
