CVE-2024-29218

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

Published Apr 15, 2024 · Updated Sep 25, 2024

Out-of-bounds write in KEYENCE KV STUDIO 11.64 and earlier allows attackers to execute code when a user opens a crafted file. The flaw also affects KV REPLAY VIEWER 2.64 and earlier and VT5-WX15/WX12 6.02 and earlier, but KEYENCE has not disclosed the file format, parsing routine, or unchecked write operation. Exploitation requires local user interaction; successful memory corruption permits information disclosure or arbitrary code execution in the affected application.
