ISC BIND 9 NSEC3-Signed Zone Handling DoS

low Nessus Plugin ID 71940

Language:

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.
