High Nessus Plugin ID 65762

Synopsis

The remote Scientific Linux host is missing one or more security updates.

Description

A denial of service flaw was found in the libdns library. A remote attacker could use this flaw to send a specially crafted DNS query to named that, when processed, would cause named to use an excessive amount of memory, or possibly crash. (CVE-2013-2266)

Note: This update disables the syntax checking of NAPTR (Naming Authority Pointer) resource records.

This update also fixes the following bug :

- Previously, rebuilding the bind-dyndb-ldap source RPM failed with a '/usr/include/dns/view.h:76:21: error:
dns/rrl.h: No such file or directory' error.

After installing the update, the BIND daemon (named) will be restarted automatically.

Solution
