I. Background BIND 9 is an implementation of the Domain Name System (DNS) protocols. The named(8) daemon is an Internet Domain Name Server. The libdns library is a library of DNS protocol support functions. II. Problem Description A flaw in a library used by BIND allows an attacker to deliberately cause excessive memory consumption by the named(8) process. This affects both recursive and authoritative servers. III. Impact A remote attacker can cause the named(8) daemon to consume all available memory and crash, resulting in a denial of service. Applications linked with the libdns library, for instance dig(1), may also be affected. IV. Workaround No workaround is available, but systems not running named(8) service and not using base system DNS utilities are not affected. V. Solution Perform one of the following: 1) Upgrade your vulnerable system to a supported FreeBSD stable or release / security branch (releng) dated after the correction date. 2) To update your vulnerable system via a source code patch: The following patches have been verified to apply to the applicable FreeBSD release branches. a) Download the relevant patch from the location below, and verify the detached PGP signature using your PGP utility. # fetch http://security.FreeBSD.org/patches/SA-13:04/bind.patch # fetch http://security.FreeBSD.org/patches/SA-13:04/bind.patch.asc # gpg --verify bind.patch.asc b) Execute the following commands as root: # cd /usr/src # patch /path/to/patch Recompile the operating system using buildworld and installworld as described in URL:http://www.FreeBSD.org/handbook/makeworld.html. Restart the named daemon, or reboot the system. 3) To update your vulnerable system via a binary patch: Systems running a RELEASE version of FreeBSD on the i386 or amd64 platforms can be updated via the freebsd-update(8) utility: # freebsd-update fetch # freebsd-update install VI.
