ISC BIND 9 Multiple Denial of Service Vulnerabilities

High Nessus Plugin ID 60120

Synopsis

The remote name server may be affected by multiple denial of service
vulnerabilities.

Description

According to its self-reported version number, the remote
installation of BIND is affected by multiple denial of service
vulnerabilities :

- Under a heavy query load, the application may use
uninitialized data structures related to failed query
cache access. This error can cause the application to
crash. Note this issue only affects the application
when DNSSEC validation is enabled. (CVE-2012-3817)

- Under a heavy, incoming TCP query load, the application
can be affected by a memory leak that can lead to
decreased performance and application termination on
systems that kill processes that are out of memory.
(CVE-2012-3868)

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-P2 / 9.7.6-P2 / 9.8.3-P2 / 9.9.1-P2 or
later.
