Bind9 9.8.0 RRSIG Query Type Remote Denial of Service Vulnerability

medium Nessus Network Monitor Plugin ID 5909


The remote DNS server is vulnerable to a denial of service attack.


The remote host is running Bind, a popular name server.

Bind9 9.8.0 is potentially affected by a denial of service vulnerability. This issue only affects BIND users who use the RPZ feature configured for RRset replacement. When RPZ is being used, a query of type RRSIG for a name configured for RRset replacement will trigger an assertion failure and cause the name server process to exit.


Upgrade to BIND 9.8.0-P1 or later.
