Technical details
The vulnerability is a classic buffer overflow in the StringToIvPFunction() routine where dimension, piece, and degree counts extracted from encoded BHV_IPF payloads are used directly as allocation sizes and loop bounds without validation. An attacker can craft a malicious payload with mismatched dimension values to cause the code to write attacker-controlled double-precision values past the end of the IvPBox weight array, resulting in heap corruption. The attack is network-reachable against systems processing untrusted IvP payloads and does not require authentication. Successful exploitation enables memory corruption and potential remote code execution.
