Arch Linux Security Warning ALSW 2007-#35
------------------------------------------------------------

Name: bind
Date: 2007-07-28
Severity: High
Warning #: 2007-#35

------------------------------------------------------------

Product Background
===================
BIND (Berkeley Internet Name Domain) is an implementation of the Domain Name 
System (DNS) protocols and provides an openly redistributable reference 
implementation of the major components of the Domain Name System

Problem Background
===================
ISC has discovered or has been notified of several bugs which can result in 
vulnerabilities of varying levels of severity in BIND as distributed by ISC.

Impact
==================
[1]The default access control lists (acls) are not being correctly set. If not 
set anyone can make recursive queries and/or query the cache contents.
[2]The DNS query id generation is vulnerable to cryptographic analysis which 
provides a 1 in 8 chance of guessing the next query id for 50% of the query 
ids. This can be used to perform cache poisoning by an attacker.
This bug only affects outgoing queries, generated by BIND 9 to answer questions 
as a resolver, or when it is looking up data for internal uses, such as when 
sending NOTIFYs to slave name servers. 


Problem Packages
===================
Package: bind
Repo: current
Group: daemon
Unsafe: < 9.4.1-P1
Safe: >= 9.4.1-P1

Package Fix
===================
Upgrade to 9.4.1-P1
