| GHSA-h89v-g948-47vp | High | Moleculer: Unauthenticated Denial of Service via negative length field in the TCP transporter packet parser### Summary The TCP transporter's packet parser (`src/transporters/tcp/parser.js`) reads the packet length field with `Buffer.prototype.readInt32BE`, a signed read. A crafted packet whose length field has the sign bit set yields a negative `length`. The parser then advances past the parsed message with `packet = packet.slice(length)`, but `Buffer.prototype.slice` clamps an out-of-range negative start index to `0`, so the buffer is returned unchanged. The `while (packet.length > 0)` loop condition therefore never becomes false, producing an infinite synchronous loop that blocks the Node.js eve |
