vm2: NodeVM zlib Buffers expose pooled host memory across the VM boundary

Summary When an application explicitly exposes Node's zlib module through vm2's NodeVM builtin allowlist, an untrusted guest can obtain a pool-backed host Buffer from zlib.deflateSync, create a full-width view of its backing ArrayBuffer, read bytes outside the compressed result, and flip a byte i...
