CVE-2023-41052

Vyper CVE-2023-41052 affects the Pythonic smart contract language Vyper. In affected versions, the evaluation order of arguments to builtins uint256_addmod, uint256_mulmod, ecadd, and ecmul does not follow source order, which can cause side effects in one argument to be relied upon by others. The...

GHSA-4HG4-9MF5-WXXQ incorrect order of evaluation of side effects for some builtins

Impact The order of evaluation of the arguments of the builtin functions uint256addmod, uint256mulmod, ecadd and ecmul does not follow source order. • For uint256addmoda,b,c and uint256mulmoda,b,c, the order is c,a,b. • For ecadda,b and ecmula,b, the order is b,a. Note that this behaviour is...

Design/Logic Flaw

Vyper is a Pythonic Smart Contract Language for the ethereum virtual machine. In versions prior to 0.3.4 when a calling an external contract with no return value, the contract address including side effects could be evaluated twice. This may result in incorrect outcomes for contracts. This issue...
