A vulnerable node, can be made to consume unbounded amounts of memory when handling specially crafted p2p messages sent from an attacker node.
The p2p handler spawned a new goroutine to respond to ping
requests. By flooding a node with ping requests, an unbounded number of goroutines can be created, leading to resource exhaustion and potentially crash due to OOM.
The fix is included in geth version 1.12.1-stable
, i.e, 1.12.2-unstable
and onwards.
Fixed by https://github.com/ethereum/go-ethereum/pull/27887
No known workarounds.
