CVE-2024-24560

Vyper is a Pythonic Smart Contract Language for the Ethereum Virtual Machine. When calls to external contracts are made, we write the input buffer starting at byte 28, and allocate the return buffer to start at byte 0 overlapping with the input buffer. When checking RETURNDATASIZE for dynamic...

GHSA-GP3W-2V2M-P686 Vyper's external calls can overflow return data to return input buffer

Summary When calls to external contracts are made, we write the input buffer starting at byte 28, and allocate the return buffer to start at byte 0 overlapping with the input buffer. When checking RETURNDATASIZE for dynamic types, the size is compared only to the minimum allowed size for that typ...
