CVE-2024-24560

CVE-2024-24560 concerns Vyper’s handling of external calls, where the return buffer can overflow into the input buffer due to memory layout and the RETURNDATASIZE length check for dynamic types. The result can cause a contract to read malformed data from the input buffer instead of the intended r...
