critical Nessus Plugin ID 147965
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.


The remote Oracle Linux host is missing a security update.


The remote Oracle Linux 8 host has packages installed that are affected by a vulnerability as referenced in the ELSA-2021-9129 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.


Update the affected packages.
