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 DNS server running on the remote host is affected by a buffer overflow vulnerability.


According to its self-reported version number, the MaraDNS server running on the remote host is affected by a heap-based buffer overflow due to improperly sanitizing user-supplied input submitted to the compress_add_dlabel_points' function in the 'Compress.c' source file.
This issue could allow a remote attacker to crash the DNS server, resulting in a denial of service or possibly code execution.


Upgrade to MaraDNS version / 1.4.06 / 2.0.02 or later or apply the relevant patch.
