ISC BIND 9 Recursive Server prefetch DoS

medium Nessus Plugin ID 73945

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. The issue exists due to an error in the 'prefetch' feature which can cause named to terminate with a 'REQUIRE' assertion failure if it processes queries whose answers have particular attributes.

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 BIND version 9.10.0-P1 or later.

Alternatively, in 'named.conf', set the 'prefetch' option to '0'.
