Synopsis

========

 

Multiple vulnerabilities have been found in BIND, the worst of which

allowing to cause remote Denial of Service.

 

Background

==========

 

BIND is the Berkeley Internet Name Domain Server.

 

Affected packages

=================

 

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

Package / Vulnerable / Unaffected

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

1 net-dns/bind < 9.7.4_p1 >= 9.7.4_p1

 

Description

===========

 

Multiple vulnerabilities have been discovered in BIND. Please review

the CVE identifiers referenced below for details.

 

Impact

======

 

The vulnerabilities allow remote attackers to cause a Denial of Service

(daemon crash) via a DNS query, to bypass intended access restrictions,

to incorrectly cache a ncache entry and a rrsig for the same type and

to incorrectly mark zone data as insecure.

 

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-9.7.4_p1"

 

NOTE: This is a legacy GLSA. Updates for all affected architectures are

available since December 22, 2011. It is likely that your system is

already

no longer affected by this issue.
