Overview
Affected versions of this package are vulnerable to Uncaught Exception via the read function in lib/read.js when processing a compressed request body that contains trailing bytes. An attacker can send a compressed body with trailing data, causing the decompression stream to emit an error on an already-finished stream with no error listener attached, which crashes the Node.js process.
