Summary: bind9 bind 9.12.3-P4bind9 bind 9.12.3-P4 (CVE-2018-5744 CVE-2018-5745 CVE-2019-6465)
Today ISC disclosed three vulnerabilities affecting multiple versions of
BIND.  Full details on versions affected and more information about the
vulnerabilities are available via these articles in the ISC Knowledge Base:

   A specially crafted packet can cause named to leak memory

   An assertion failure can occur if a trust anchor rolls over to
   an unsupported key algorithm when a server is using managed-keys

   Controls for zone transfers may not be properly applied to
   Dynamically Loadable Zones (DLZs) if the zones are writable.

New software versions are available from the ISC downloads page:

With the public disclosure of these vulnerabilities, parties which
had been given advance notice concerning them are released from
non-disclosure and packagers and redistributors are encouraged to
publish updated packages containing fixes.

If you have additional questions, please direct them to

Thank you,

Michael McNally
ISC Security Officer
