MEDIUM 6.9EPSS 0.65%

Does this matter?

Lower severity and a low EPSS score (0.65%). Track it; it rarely justifies an emergency change on its own.

Description

go-ethereum (geth) is a golang execution layer implementation of the Ethereum protocol. Prior to version 1.17.0, an attacker can cause high memory usage by sending a specially-crafted p2p message. The issue is resolved in the v1.17.0 release.
