New submission from Guillaume <[email protected]>:
pickle.load() raises a criptic SystemError with malformed input, whereas I
would have expected an UnpicklingError.
"SystemError: deallocated bytearray object has exported buffers"
Because pickle is not meant for use on untrusted input, this likely would not
be considered a servere issue.
Reproducing:
import pickle
f = open("crash-95c0cb965cb66f5eebc778a1d2304eaffb72f1aa", "rb")
d = pickle.load(f)
