ISC BIND 9 Zero-Length RDATA Section Denial of Service / Information Disclosure

high Nessus Plugin ID 59446

Synopsis

The remote name server may be affected by a denial of service / information disclosure vulnerability.

Description

According to its self-reported version number, the remote installation of BIND does not properly handle resource records with a zero-length RDATA section, which may lead to unexpected outcomes, such as crashes of the affected server, disclosure of portions of memory, corrupted zone data, or other problems.

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-P1 / 9.7.6-P1 / 9.8.3-P1 / 9.9.1-P1 or later.
