Synopsis ========
Multiple vulnerabilities have been found in BIND, the worst of which may allow remote Denial of Service.
Background ==========
BIND is the Berkeley Internet Name Domain Server.
Affected packages =================
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 net-dns/bind < 9.9.1_p3 >= 9.9.1_p3
Description ===========
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.
Resolution ==========
All BIND users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=net-dns/bind-9.9.1_p3"
