Synopsis
========
Several cache poisoning vulnerabilities have been found in BIND.
Background
==========
ISC BIND is the Internet Systems Consortium implementation of the
Domain Name System (DNS) protocol.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 net-dns/bind < 9.4.3_p5 >= 9.4.3_p5
Description
===========
Multiple cache poisoning vulnerabilities were discovered in BIND. For
further information please consult the CVE entries and the ISC Security
Bulletin referenced below.
Note: CVE-2010-0290 and CVE-2010-0382 exist because of an incomplete
fix and a regression for CVE-2009-4022.
Impact
======
An attacker could exploit this weakness to poison the cache of a
recursive resolver and thus spoof DNS traffic, which could e.g. lead to
the redirection of web or mail traffic to malicious sites.
Workaround
==========
There is no known workaround at this time.
Resolution
==========
All BIND users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=net-dns/bind-9.4.3_p5"
