MaraDNS < 2.0.13 Multiple Vulnerabilities

high Nessus Plugin ID 86674
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.

Synopsis

The DNS server running on the remote host is affected by multiple vulnerabilities.

Description

According to its self-reported version number, the MaraDNS server running on the remote host is prior to 2.0.13. It is, therefore, potentially affected by multiple vulnerabilities :

- A flaw exists in mararc parser due to a buffer underflow condition in the file ParseMaraRc.c. An unauthenticated, remote attacker can exploit this to read from disallowed memory locations.

- A flaw exists in the Deadwood recursive resolver component due to a buffer underflow condition that can allow an out-of-bounds memory location to be overwritten by the output of malloc(). An unauthenticated, remote attacker can exploit this issue to cause a denial of service.

Solution

Upgrade to MaraDNS version 2.0.13 or later
