yasm 1.3.0.55.g101bc was discovered to contain a stack overflow via the function parse_expr1 at /nasm/nasm-parse.c. Note: This has been disputed by third parties who argue this is a bug and not a security issue because yasm is a standalone program not designed to run untrusted code.
AnalysisAI
yasm 1.3.0.55.g101bc was discovered to contain a stack overflow via the function parse_expr1 at /nasm/nasm-parse.c. Rated medium severity (CVSS 5.5), this vulnerability is no authentication required, low attack complexity. Public exploit code available and no vendor patch available.
Technical ContextAI
This vulnerability is classified as Out-of-bounds Write (CWE-787), which allows attackers to write data beyond allocated buffer boundaries leading to code execution or crashes. yasm 1.3.0.55.g101bc was discovered to contain a stack overflow via the function parse_expr1 at /nasm/nasm-parse.c. Note: This has been disputed by third parties who argue this is a bug and not a security issue because yasm is a standalone program not designed to run untrusted code. Affected products include: Yasm Project Yasm.
RemediationAI
No vendor patch is available at time of analysis. Monitor vendor advisories for updates. Validate write boundaries, use memory-safe languages, enable compiler protections (ASLR, stack canaries).
