CVE-2023-40591

Estado: ModificadaAlta (7.5)—

go-ethereum (geth) is a golang execution layer implementation of the Ethereum protocol. A vulnerable node, can be made to consume unbounded amounts of memory when handling specially crafted p2p messages sent from an attacker node. The fix is included in geth version `1.12.1-stable`, i.e, `1.12.2-unstable` and onwards. Users are advised to upgrade. There are no known workarounds for this vulnerability.
