Out-of-bounds Read in Ethereum Virtual Machine
CVE-2017-14457
An exploitable information leak/denial of service vulnerability exists in the libevm (Ethereum Virtual Machine) `create2` opcode handler of CPP-Ethereum. A specially crafted smart contract code can cause an out-of-bounds read leading to memory disclosure or denial of service. An attacker can create/send malicious a smart contract to trigger this vulnerability.
