Overview
Affected versions of this package are vulnerable to Heap-based Buffer Overflow in the Crypto_TM_ProcessSecurity() function in crypto_tm.c, which may exceed len_ingest. An attacker can overwrite adjacent heap memory and cause a potentially exploitable crash by manipulating the Secondary Header Length to exceed the packet's total length during a memcpy operation.
