GHSA-HMJ8-5XMH-5573 libp2p: yamux connection DoS via oversized data frame

Summary The yamux stream multiplexer in py-libp2p does not validate incoming DATA frame lengths against the receive window before reading the frame body. Any peer that completes a standard libp2p handshake can send a single 12-byte frame claiming a 4 GB body, causing the victim's yamux read loop ...

brace-expansion: DoS via unbounded expansion length causing an out-of-memory process crash

Summary expand bounds the number of results it produces the max option, 100000 by default but not their length. By chaining many brace groups, an attacker keeps the result count under max while making every result grow with the number of groups. Building max long results — plus the intermediate...
