"On October 25, 2021, a vulnerability in all prior versions of Geth was discovered that permitted a carefully crafted peer-to-peer message to inflict a denial-of-service attack on the receiving node. 42 From our crawls of the Bitcoin network, we observe that 21% of Bitcoin nodes are running an old version of the Bitcoin Core client that is known to be vulnerable." The beginning of this excerpt is talking about Geth, and how unpatched Geth resulted in a fork of Ethereum. Then, out of nowhere they indicated 21% of Bitcoin nodes are vulnerable and running an old version of the bitcoin core client, and they bold it. They didn't say anything about this vulnerability in the preceding paragraph. Vulnerable to what? Certainly not vulnerable to the same thing that Geth exploit took advantage of.
