Vyper is a Pythonic Smart Contract Language for the EVM. There is an error in the stack management when compiling the `I

Vyper is a Pythonic Smart Contract Language for the EVM. There is an error in the stack management when compiling the IR for sha3_64. Concretely, the height variable is miscalculated.

The vulnerability can't be triggered without writing the IR by hand (that is, it cannot be triggered from regular vyper code). sha3_64 is used for retrieval in mappings. No flow that would cache the key was found so the issue shouldn't be possible to trigger when compiling the compiler-generated IR. This issue isn't triggered during normal compilation of vyper code so the impact is low.

At the time of publication there is no patch available.
