ISC BIND Assertion Error Resource Record RDATA Query Parsing Remote DoS

high Nessus Plugin ID 62119

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 will exit with an assertion failure if a resource record with RDATA in excess of 65535 bytes is loaded and then subsequently queried. 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-P3 / 9.6-ESV-R8 / 9.7.6-P3 / 9.7.7 / 9.8.3-P3 / 9.8.4 / 9.9.1-P3 / 9.9.2 or later.
