AnalysisAI
wasm3 v0.5.0 was discovered to contain a global buffer overflow which leads to segmentation fault via the function "PreserveRegisterIfOccupied" in wasm3/source/m3_compile.c. Rated high severity (CVSS 7.5), this vulnerability is remotely exploitable, no authentication required, low attack complexity. Public exploit code available and no vendor patch available.
Technical ContextAI
This vulnerability is classified as Buffer Copy without Size Check (CWE-120), which allows attackers to overflow a buffer to corrupt adjacent memory. wasm3 v0.5.0 was discovered to contain a global buffer overflow which leads to segmentation fault via the function "PreserveRegisterIfOccupied" in wasm3/source/m3_compile.c. Affected products include: Wasm3 Project Wasm3.
RemediationAI
No vendor patch is available at time of analysis. Monitor vendor advisories for updates. Always validate buffer sizes before copy operations. Use bounded functions (strncpy, snprintf). Enable compiler protections.
