Description
Today I got a message from https://nodesecurity.io:
142 - Buffer Overread
Vulnerable: All - Patched: None - Path: multer@1.3.0 > concat-stream@1.6.0
How to fix
Consider using the --zero-fill-buffers command line argument to zero out buffer before using them.
Avoid passing numeric values to the write function.

Research direction
Review concat-stream's write handling and the multer@1.3.0 > concat-stream@1.6.0 dependency path, starting with the advisory's guidance about numeric values and zero-filled buffers. The issue does not name a file, test, or specific expected behavior, so the completion criteria need to be clarified before implementation.
