Overview
vyper is a Pythonic Smart Contract Language for the EVM.
Affected versions of this package are vulnerable to Improper Check or Handling of Exceptional Conditions due to a failure to verify the success flag of calls to the precompiles EcRecover (0x1) and Identity (0x4). An attacker can exploit this by providing a specific amount of gas to intentionally make these calls fail while allowing the overall execution to continue.
