Language:

Synopsis

The DNS server running on the remote host is affected by a denial of service vulnerability.

Description

According to its self-reported version number, the MaraDNS server running on the remote host is affected by an issue during resource record rotation. This issue could allow a remote attacker to send a specially crafted packet, which will prevent an authoritative CNAME record from resolving, resulting in a denial of service.

Note that if the line 'max_ar_chain = 2' is in the configuration file, the host is not affected.

Solution

Upgrade to MaraDNS version 1.0.41 / 1.2.12.08 / 1.3.07.04 or later or refer to the vendor for a workaround.
