Insufficient bounds checking in ASP may allow an
attacker to issue a system call from a compromised ABL which may cause
arbitrary memory values to be initialized to zero, potentially leading to a
loss of integrity.

Certain size values in firmware binary headers
could trigger out of bounds reads during signature validation, leading to
denial of service or potentially limited leakage of information about
out-of-bounds memory contents.
