Hi. http://www.debian.org/security/2011/dsa-2347 There is updated packages for Debian (and Ubuntu) already. Do you know how long until Centos release an update to bind ? I have looked here and couldn't see any info - http://lists.centos.org/pipermail/centos-announce/2011-November/thread.html - Is this the correct place to look for security update info ? Cheers !
