Synopsis

Background

BIND is the Berkeley Internet Name Domain Server.

Affected packages

Package	Vulnerable	Unaffected	Architecture(s)
net-dns/bind	< 9.7.4_p1	>= 9.7.4_p1	All supported architectures

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.
