Overview
Affected versions of this package are vulnerable to Heap-based Buffer Overflow via the Crypto_TC_Check_IV_Setup function. An attacker can cause heap memory corruption and potentially execute arbitrary code or crash the application by supplying a specially crafted telecommand frame that results in writing past the end of a heap buffer.
