Synopsis
The remote CentOS host is missing one or more security updates.Description
Updated bind97 packages that fix two security issues are now available for Red Hat Enterprise Linux 5.The Red Hat Security Response Team has rated this update as having important security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section.
The Berkeley Internet Name Domain (BIND) is an implementation of the Domain Name System (DNS) protocols. BIND includes a DNS server (named); a resolver library (routines for applications to use when interfacing with DNS); and tools for verifying that the DNS server is operating correctly.
A flaw was found in the way BIND handled zero length resource data records. A malicious owner of a DNS domain could use this flaw to create specially crafted DNS resource records that would cause a recursive resolver or secondary server to crash or, possibly, disclose portions of its memory. (CVE-2012-1667)
A flaw was found in the way BIND handled the updating of cached name server (NS) resource records. A malicious owner of a DNS domain could use this flaw to keep the domain resolvable by the BIND server even after the delegation was removed from the parent DNS zone. With this update, BIND limits the time-to-live of the replacement record to that of the time-to-live of the record being replaced. (CVE-2012-1033)
Users of bind97 are advised to upgrade to these updated packages, which correct these issues. After installing the update, the BIND daemon (named) will be restarted automatically.
