CVE-2020-26264 (GCVE-0-2020-26264)

Vulnerability from cvelistv5 – Published: 2020-12-11 16:45 – Updated: 2024-08-04 15:56

Title

LES Server DoS via GetProofsV2

Summary

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.

Severity

6.5 (Medium)
