ISC BIND 9 Recursive Response DNAME Record Handling DoS

Medium Nessus Plugin ID 94577

Synopsis

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

Description

According to its self-reported version number, the instance of ISC BIND 9 running on the remote name server is affected by a denial of service vulnerability due to improper handling of a recursive response containing a DNAME record in the answer section. An unauthenticated, remote attacker can exploit this to cause an assertion failure and daemon exit.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Upgrade to ISC BIND version 9.9.9-P4 / 9.9.9-S6 / 9.10.4-P4 / 9.11.0-P1 or later.
