Ethereum client Besu fixes five security flaws found by CertiK

Ethereum client Besu fixed five security vulnerabilities identified by blockchain security firm CertiK in version 26.7.1, released on July 27, and later published four detailed security advisories on Aug. 14. The vulnerability details were held back at first to give node operators time to upgrade. CertiK Security Engineering Director and Senior Audit Partner Jialiang Chang said the patch-first approach created an 18-day window for operators to identify affected deployments, test the new release and coordinate upgrades with validators or consortium participants. The issues touched block propagation handling, caching of future-height consensus proposals, WebSocket subscription limits and JSON-RPC filter creation. If left unpatched, an attacker could exhaust node memory or thread resources, affecting node availability and consensus processing. CertiK said it used its Chain Scan method to run adversarial testing against peer-to-peer, HTTP RPC, WebSocket RPC and consensus interfaces in a private multi-node test network, and provided reproducible test tools to the Besu team.
