ISC BIND Memory Leak DoS Vulnerability

high Nessus Plugin ID 122505


The remote name server is affected by a Memory Leak DoS vulnerability.


According to its self-reported version, the instance of ISC BIND 9 running on the remote name server is less than 9.11.5-P4 / 9.11.5-S5 / 9.12.3-P4 / 9.13.7. It is, therefore, affected by a denial of service vulnerability.

- A memory leak vulnerability exists for named's memory use. An unauthenticated, remote attacker can cause named's memory use to grow without bounds until all memory available to the process is exhausted. (CVE-2018-5744)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.


Upgrade to ISC BIND version 9.11.5-P4 / 9.12.3-P4 / 9.13.7 or later.
