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 version of Apple iOS running on the mobile device is affected by multiple vulnerabilities.


The version of Apple iOS running on the mobile device is prior to 14.7. It is, therefore, affected by multiple vulnerabilities including the following:

- An unspecified vulnerability in Measure affecting availability, confidentiality and availability vectors.

- A stack overflow vulnerability in FontParser which was addressed with improved input validation. (CVE-2021-30759)

- An integer overflow vulnerability in FontParser which was addressed through improved input validation.

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