If you suspect you have found a security defect in BIND 9, ISC DHCP, or Kea DHCP, or if you wish to inquire about a security issue that you have learned about which has not yet been publicly announced, please contact our Security Officer via email at firstname.lastname@example.org. However, plain-text e-mail is not a secure choice for communications concerning undisclosed security issues, so we ask that you please encrypt your communications to us using the ISC Security Officer public key.
More information is available about How to Submit a Bug Report.

Reporting a Bug That Is NOT a Security Vulnerability
- Please report bugs in BIND 9 by opening an issue in our BIND GitLab.
- Please report bugs in Kea at our Kea GitLab.
- Please report ISC DHCP bugs at our ISC DHCP GitLab.
Ensuring You Are Not Running Software With a Known Vulnerability
To ensure that you are notified of any new discovered vulnerabilities, you should become an ISC support subscriber, which entitles you to advance notification of security vulnerabilities via a secure, private support queue.
ISC uses the CVSS calculator, a program of first.org and NIST, to determine the severity of potential security issues.
