Description

BIND (Berkeley Internet Name Domain) is an implementation of the DNS(Domain Name System) protocols.A flaw was discovered in the way BIND checked the return value of theOpenSSL DSA_do_verify function. On systems using DNSSEC, a malicious zonecould present a malformed DSA certificate and bypass proper certificatevalidation, allowing spoofing attacks. (CVE-2009-0025)For users of Red Hat Enterprise Linux 3 this update also addresses a bugwhich can cause BIND to occasionally exit with an assertion failure.All BIND users are advised to upgrade to the updated package, whichcontains a backported patch to resolve this issue. After installing theupdate, BIND daemon will be restarted automatically.
