high Nessus Plugin ID 147943


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 Fedora host is missing one or more security updates.


The remote Fedora 33 host has a package installed that is affected by a vulnerability as referenced in the FEDORA-2021-acd448b558 advisory.

- With the upgrade of python-cryptography in f33+, the PKCS7_get0_clients api was dropped. It has been replaced by a cleaner and easier api, which roca-detect now uses. The consequence was that PKCS7 keys would be silently ignored. To test, run $ roca-detect /usr/lib/python3.*/site- packages/roca/tests/data/pkcs701.p7s It should see 1 PKCS7 key. (FEDORA-2021-acd448b558)

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 roca-detect package.
