Synopsis

The remote name server may be affected by a denial of service vulnerability.

Description

According to its self-reported version number, the remote installation of BIND is potentially affected by a denial of service vulnerability. If an attacker sends a specially crafted request to a BIND server it may cause the name server process to crash.

Note that Nessus has only relied on the version itself and has not attempted to determine whether or not the install is actually vulnerable.

Solution

Upgrade to BIND 9.6-ESV-R4-P3 / 9.7.3-P3 / 9.8.0-P4 or later.
