According to a commenter, this should provide a temporary countermeasure:
iptables -A INPUT -p udp --dport 53 -j DROP -m u32 --u32 '30>>27&0xF=5'
Haven't tested it, would like to know the results...
Well, good point, but Centos does not ship libipt_u32.so. Even more Centos 4.x is now undergoing rebuild process, so no updates even security updates are being released. Which is something I can accept.
Those looking for patched bind for Centos 4.x may use packages I have built with CVE-2009-0696 patch. http://fs12.vsb.cz/hrb33/el4/hrb/testing/i386/repoview/letter_b.group.html http://fs12.vsb.cz/hrb33/el4/hrb/testing/x86_64/repoview/letter_b.group.html
Well done, David but there's a little problem with those rpms: Preparing... ########################################### [100%] package bind-libs-9.2.4-30.el4_7.2 (which is newer than bind-libs-9.2.4-30.el4.hrb.2.1) is already installed package bind-utils-9.2.4-30.el4_7.2 (which is newer than bind-utils-9.2.4-30.el4.hrb.2.1) is already installed package bind-9.2.4-30.el4_7.2 (which is newer than bind-9.2.4-30.el4.hrb.2.1) is already installed package bind-chroot-9.2.4-30.el4_7.2 (which is newer than bind-chroot-9.2.4-30.el4.hrb.2.1) is already installed Maybe you can bump the version a bit.
