ISC BIND 9 resolver.c Multiple DNS Cookie Packet Handling DoS

High Nessus Plugin ID 90000

Synopsis

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

Description

According to its self-reported version number, ISC BIND installed on the remote name server is affected by a denial of service vulnerability in file resolver.c when DNS cookies are enabled. An unauthenticated, remote attacker can exploit his, via a malformed packet with more than one cookie option, to cause an INSIST 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 9.10.3-P4 or later.
