Name of the Vulnerable Software and Affected Versions
Go Ethereum (aka geth) version 1.8.19
Description
The issue allows attackers to cause a denial of service due to memory consumption. This can be achieved by rewriting the length of a dynamic array in memory and then writing data to a single memory location with a large index number. An example of this exploit involves using
assembly { mstore } followed by a c[0xC800000] = 0xFF assignment.Recommendations
For Go Ethereum (aka geth) version 1.8.19, update to a newer version that contains a fix for this issue to prevent denial of service attacks.
