ISC BIND 9 RDATA Section Handling DoS

high Nessus Plugin ID 69106

Language:

Synopsis

The remote name server is prone to a denial of service attack.

Description

According to its self-reported version number, the remote installation of BIND can be forced to crash via specially crafted queries containing malformed 'rdata' contents.

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

Further note that this vulnerability is being actively exploited at the time of this writing.

Solution

Upgrade to BIND version 9.9.3-S1-P1 / 9.9.3-P2 / 9.8.5-P2 or later, or apply the vendor-supplied patch.

In the case of development branches, such as 9.8.6rc1 / 9.9.4rc1 / 9.9.4-S1rc1, no patch is currently available.
