ISC BIND 9.9.8 < 9.9.8-P2 / 9.10.3 < 9.10.3-P2 Socket Error Handling DoS

high Nessus Plugin ID 87503
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.


The remote name server is affected by a denial of service vulnerability.


According to its self-reported version number, the remote installation of BIND is affected by a denial of service vulnerability due to a race condition that occurs when handling socket errors. An unauthenticated, remote attacker can exploit this to trigger an INSIST failure, resulting in a denial of service condition.

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


Upgrade to BIND version 9.9.8-P2 / 9.9.8-S3 / 9.10.3-P2 or later.
Note that 9.9.8-S3 is a preview version of BIND provided exclusively to ISC Support customers.
