The BIND versions listed in this article are EOL

This BIND 9 Security Vulnerability Matrix is a record of vulnerabilities affecting the EOL BIND 9.5 branch during (or very shortly after) its lifetime.  It is known to be affected by some vulnerabilities discovered after the EOL date (September 2010) but they will not be listed here.

This article has two parts

  • The first part is a table listing all of the vulnerabilities covered by this page.  The first column is a reference number for use in the tables in the second part.  The second column is the CVE (Common Vulnerabilities and Exposure) number for the vulnerability, linked to its page on  The third column is a short description of the vulnerability, linked (where possible) to our Knowledge Base article on the vulnerability.
  • The second part is a table listing all of the releases in this branch along the side and vulnerabilities along the top.  If a vulnerability number is less than the lowest column heading, that branch does not have any versions with it.  If a vulnerability number is greater than the highest column heading, that branch has not been tested and should be assumed to be vulnerable.

See the matrix for current branches for more information about how to interpret these tables.

We do not generally list alpha, beta or release candidate (RC) versions here, and recommend that you use only released software in any environment in which security could be an issue. This page explains our version numbering system.

Using obsolete versions of BIND

We recommend that you not use obsolete versions of any ISC software. It was updated for a reason.
