BIND: Multiple vulnerabilities

BIND: Multiple vulnerabilities Multiple vulnerabilities have been found in BIND, the worst of which may allow remote Denial of Service. bind 2012-09-24 2012-09-24: 1 402661 419637 427966 434876 remote 9.9.1_p3 9.9.1_p3

BIND is the Berkeley Internet Name Domain Server.

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).

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.

There is no known workaround at this time.

All BIND users should upgrade to the latest version:


      # emerge --sync
      # emerge --ask --oneshot --verbose ">=net-dns/bind-9.9.1_p3"
