CVE-2024-24559
Good to know:
Date: February 5, 2024
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.
