CVE-2024-29219

Code execution via crafted-file out-of-bounds read

Published Apr 15, 2024 · Updated Sep 19, 2025

Out-of-bounds read in affected KEYENCE software allows attackers to disclose data or execute code when a crafted file is opened. KV STUDIO 11.64 and earlier, KV REPLAY VIEWER 2.64 and earlier, and VT5-WX15/WX12 6.02 and earlier read beyond a buffer boundary while parsing the file; KEYENCE has not disclosed the specific parser or file format. Execution requires a user to open the crafted file, and the documented consequences are information disclosure or arbitrary code execution.
