ISC BIND 9 DNS RDATA Handling DoS

high Nessus Plugin ID 62562

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 can become locked up if certain combinations of RDATA are loaded into the server. 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 9.6-ESV-R7-P4 / 9.6-ESV-R8 / 9.7.6-P4 / 9.7.7 / 9.8.3-P4 / 9.8.4 / 9.9.1-P4 / 9.9.2 or later.
