MOOS-IvP through 24.8.1 contains a buffer overflow vulnerability in StringToIvPFunction() where dimension, piece, and degree counts from encoded BHV_IPF payloads are used as allocation sizes and loop bounds without validation. Attackers can supply crafted payloads with mismatched dimension values to write attacker-controlled doubles past the end of the IvPBox weight array, causing memory corruption and potential code execution.
