What is CVE-2021-32471?

The Universal Turing Machine, specifically in its 1967 implementation by Intrinsic Propensity, is affected by insufficient input validation. This issue allows users to execute arbitrary code through carefully crafted input data that alters the expected behavior of the system. An example is when a tape head could end up in an unexpected location while processing inputs consisting of 'A's and 'B's instead of the intended binary '0's and '1's. Although noted that this vulnerability has no real-world implications, it is essential to be aware of such weaknesses in software design.
