ISC BIND 9 NSEC3-Signed Zone Handling DoS

low Nessus Plugin ID 71940
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 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 affected by a denial of service vulnerability. This issue exists due to the handling of queries for NSEC3-signed zones related to the memcpy() function in the 'name.c' file on authoritative nameservers.

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

Solution

Upgrade to BIND version 9.9.5 / 9.9.4-P2 / 9.8.7 / 9.8.6-P2 / 9.6-ESV-R11 / 9.6-ESV-R10-P2 or later.
