BIND 9 Software Vulnerability Matrix - 9.18

Prev Next
SECURITY WARNING

BIND 9.18 is obsolete. Obsolete versions of BIND are all known to be vulnerable. ISC strongly recommends upgrading to a current version as soon as practical.

The obsolete matrices will not be updated to reflect new vulnerabilities. You must assume you are vulnerable if you are running an obsolete version.

The BIND 9 Software Vulnerability Matrix details known security vulnerabilities in version 9.18 of BIND during that branch's support life. Vulnerabilities are identified by their CVE ID: Common Vulnerabilities and Exposures.

For current versions of BIND, see the main BIND 9 Software Vulnerability Matrix.

Using this matrix

Each row with a CVE ID gives the version(s) that fix that problem.

Determining vulnerability

To determine if/how a given version is vulnerable:

  • Find the column heading for the corresponding branch (9.X version)
  • Read down that column to find the specific 9.X.Y version (or use "Find" in your browser)

To determine if a given CVE applies:

Once you find a given table row (CVE ID and/or version):

  • The listed version(s) contain fixes for that CVE, and are not vulnerable to that CVE
  • A dash (-) indicates no version of that branch (column) is vulnerable to that CVE (row)
  • That version is vulnerable to later CVEs (above the row)
  • That version is not vulnerable to earlier CVEs (below the row)

For table rows without a CVE:

  • A dash (-) indicates that row does not apply to that branch (column)

Supported Preview Edition

  • Most CVEs apply equally to both the open source edition and the Supported Preview Edition (-S).
  • If a row lists the -S1 suffix, the CVE applies only to the Supported Preview Edition.
  • If no -S1 suffix is present, the CVE applies to both editions.

The matrix

Each row with a CVE ID gives the version(s) that fix that problem.
