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 host is vulnerable to a buffer overflow.


The installed version of SeaMonkey is earlier than 1.1.16. An XSL transformation vulnerability in such versions can be leveraged with a specially crafted stylesheet to crash the browser or to execute arbitrary code.


Upgrade to version 1.1.16 or higher.
