ISC BIND 9 Unspecified Packet Processing Remote DoS

medium Nessus Network Monitor Plugin ID 5982
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 remote DNS server is vulnerable to a denial of service attack.

Description

The remote host is running Bind, a popular name server.

Versions of BIND 9.6 earlier than 9.6-ESV-R4-P3, 9.7 earlier than 9.7.3-P3, and 9.8 earlier than 9.8.0-P4 are 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.

Solution

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