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 FreeBSD host is missing a security-related update.


Matthieu Herrb reports : Problem Description : Several vulnerabilities have been identified in xfs, the X font server. The QueryXBitmaps and QueryXExtents protocol requests suffer from lack of validation of their 'length' parameters. Impact : On most modern systems, the font server is accessible only for local clients and runs with reduced privileges, but on some systems it may still be accessible from remote clients and possibly running with root privileges, creating an opportunity for remote privilege escalation.


Update the affected package.
