CVE-2020-26264

Go Ethereum, or "Geth", is the official Golang implementation of the Ethereum
protocol. In Geth before version 1.9.25 a denial-of-service vulnerability can
make a LES server crash via malicious GetProofsV2 request from a connected LES
client. This vulnerability only concerns users explicitly enabling les server;
disabling les prevents the exploit. The vulnerability was patched in version
1.9.25.
