Description Sam James archtester Gentoo Infrastructure gentoo-dev Security 2020-12-16 06:18:59 UTC
* CVE-2020-26265

A consensus-vulnerability in Geth could cause a chain split, where vulnerable versions refuse to accept the canonical chain.

* CVE-2020-26264

A DoS vulnerability can make a LES server crash via malicious GetProofsV2 request from a connected LES client.

* CVE-2020-26242

Denial-of-service (crash) during block processing.

* CVE-2020-26241

This is a Consensus vulnerability, which can be used to cause a chain-split where vulnerable nodes reject the canonical chain.

* CVE-2020-26240

An ethash mining DAG generation flaw in Geth could cause miners to erroneously calculate PoW in an upcoming epoch (estimated early January, 2021). This happened on the ETC chain on 2020-11-06. This issue is relevant only for miners, non-mining nodes are unaffected.
