Detailsinfo

A vulnerability has been found in Go Ethereum up to 1.8.10 and classified as problematic. This vulnerability affects the function GetBlockHeadersMsg of the component LES Protocol. The manipulation with an unknown input leads to a array index vulnerability. The CWE definition for the vulnerability is CWE-129. The product uses untrusted input when calculating or using an array index, but the product does not validate or incorrectly validates the index to ensure the index references a valid position within the array. As an impact it is known to affect availability. CVE summarizes:

The GetBlockHeadersMsg handler in the LES protocol implementation in Go Ethereum (aka geth) before 1.8.11 may lead to an access violation because of an integer signedness error for the array index, which allows attackers to launch a Denial of Service attack by sending a packet with a -1 query.Skip value. The vulnerable remote node would be crashed by such an attack immediately, aka the EPoD (Ethereum Packet of Death) issue.

The bug was discovered 06/05/2018. The weakness was shared 07/05/2018 (Website). The advisory is available at github.com. This vulnerability was named CVE-2018-12018 since 06/07/2018. The exploitation appears to be easy. The attack can be initiated remotely. No form of authentication is required for a successful exploitation. Technical details are known, but there is no available exploit.

The vulnerability was handled as a non-public zero-day exploit for at least 29 days. During that time the estimated underground price was around $0-$5k.

Upgrading to version 1.8.11 eliminates this vulnerability.
