GHSA-7VRM-3JC8-5WWM Incorrect Comparison in Vyper

Impact bytestrings can have dirty bytes in them, resulting in the word-for-word comparison to give incorrect results, e.g. vyper b1: Bytes32 = b"abcdef" b1 = sliceb1, 0, 1 b2: Bytes32 = b"abcdef" t: bool = b1 == b2 incorrectly evaluates to True even without dirty nonzero bytes, because there is n...
