CVE-2017-14451
An exploitable out-of-bounds read vulnerability exists in libevm (Ethereum Virtual Machine) of CPP-Ethereum.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (2.65%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
An exploitable out-of-bounds read vulnerability exists in libevm (Ethereum Virtual Machine) of CPP-Ethereum. A specially crafted smart contract code can cause an out-of-bounds read which can subsequently trigger an out-of-bounds write resulting in remote code execution.
