Centos 6 patching bind for bind bug CVE-2015-5477

In order to patch centos 6 for bind bug CVE-2015-5477 it is necessary to use the CR (continuous release) repository as it is not available for 6.6 and will be released in 6.7 and thus must be installed as a hot fix.

To do this simple enable the CR repository

# yum install centos-release-cr

Then update bind

# yum update bind

For good measure restart bind

# service named restart

And then I suggest you remvoe the CR repository

# yum erase centos-release-cr

You can check which repositories are in use

# yum repolist
