"The remote Oracle Linux 8 host has packages installed that are affected by a vulnerability as referenced in the
ELSA-2021-9130 advisory.

  - Python 3.x through 3.9.1 has a buffer overflow in PyCArg_repr in _ctypes/callproc.c, which may lead to
    remote code execution in certain Python applications that accept floating-point numbers as untrusted
    input, as demonstrated by a 1e300 argument to c_double.from_param. This occurs because sprintf is used
    unsafely. (CVE-2021-3177)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
