(Red Hat Issues Fix) BIND Lightweight Resolution Bug in Processing Long Queries Lets Remote Users Cause the Target Service to Crash
SecurityTracker Alert ID:  1039223
SecurityTracker URL:  http://securitytracker.com/id/1039223
CVE Reference:   CVE-2016-2775   (Links to External Site)
Date:  Aug 24 2017
Impact:   Denial of service via network
Fix Available:  Yes  Vendor Confirmed:  Yes  
Version(s): 9.0.x - 9.9.9-P1, 9.10.0 - 9.10.4-P1, 9.11.0a3 - 9.11.0b1
Description:   A vulnerability was reported in BIND. A remote user can cause the target service to crash.

A remote user can send a specially crafted request with a query name and a search list entry that exceeds the maximum allowable length to cause the target BIND server to crash.

Systems using the lightweight resolution protocol via either the 'lwresd' utility or via named using the "lwres" statement in 'named.conf' are affected.

Impact:   A remote user can cause the target service to crash.
Solution:   Red Hat has issued a fix.

3. Description:

The Berkeley Internet Name Domain (BIND) is an implementation of the Domain
Name System (DNS) protocols. BIND includes a DNS server (named); a resolver
library (routines for applications to use when interfacing with DNS); and
tools for verifying that the DNS server is operating correctly.

Security Fix(es):

* It was found that the lightweight resolver protocol implementation in
BIND could enter an infinite recursion and crash when asked to resolve a
query name which, when combined with a search list entry, exceeds the
maximum allowable length. A remote attacker could use this flaw to crash
lwresd or named when using the "lwres" statement in named.conf.
(CVE-2016-2775)

4. Solution:

For details on how to apply this update, which includes the changes
described in this advisory, refer to:

https://access.redhat.com/articles/11258

After installing the update, the BIND daemon (named) will be restarted
automatically.
