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 using a version of Mozilla or Mozilla Thunderbird that is vulnerable to a heap overflow vulnerability. A heap overflow has been reported for the Mozilla POP3 mail handler routines. An attacker controlled POP3 server may be able to execute arbitrary code on the client machine.


Upgrade to Mozilla 1.7.1 / Thunderbird 0.7.1 or higher.
