Detailed Description |
According to its self-reported version number, the installation of ISC BIND running on the remote name server is version 9.15.6 prior to 9.16.6 or 9.17.x prior to 9.17.4. It is, therefore, affected by a denial of service (DoS) vulnerability due to an incorrectly specified maximum buffer size. An unauthenticated, remote attacker can exploit this issue by sending a specially crafted large TCP payload to trigger an assertion failure, causing the server to exit.
