CVE-2020-26264 LES Server DoS via GetProofsV2

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...

CVE-2020-26264

Go Ethereum (Geth) before v1.9.25 is vulnerable to a denial-of-service affecting the LES server via a malicious GetProofsV2 request from a connected LES client. The issue only concerns users who explicitly enable the LES server; disabling LES prevents exploitation. The vulnerability was fixed in ...

CVE-2020-26265

Go Ethereum (Geth) up to v1.9.19 (inclusive) is affected by a consensus vulnerability that could lead to a chain split where non-canonical chains are rejected. The issue stems from how state/account creation interacted with deleted accounts, causing inconsistent consensus under certain transactio...

CVE-2017-14451

CVE-2017-14451 is an exploitable out-of-bounds read in libevm (CPP‑Ethereum). The root cause, per TALOS/Red Hat/NVD details, is the pow2N function returning exp[_n] without bounds checks, with exp defined as size 6. The _type parameter (0–255) can drive laneCount/laneWidth to values beyond the ar...
