Synopsis

The remote Gentoo host is missing one or more security-related patches.

Description

The remote host is affected by the vulnerability described in GLSA-201209-04 (BIND: Multiple vulnerabilities)

Multiple vulnerabilities have been discovered in BIND:
Domain names are not properly revoked due to an error in the cache update policy (CVE-2012-1033).
BIND accepts records with zero-length RDATA fields (CVE-2012-1667).
An assertion failure from the failing-query cache could occur when DNSSEC validation is enabled (CVE-2012-3817).
A memory leak may occur under high TCP query loads (CVE-2012-3868).
An assertion error can occur when a query is performed for a record with RDATA greater than 65535 bytes (CVE-2012-4244).
Impact :

A remote attacker may be able to cause a Denial of Service condition or keep domain names resolvable after it has been deleted from registration.
Workaround :

There is no known workaround at this time.

Solution

All BIND users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=net-dns/bind-9.9.1_p3'
