AIX 7.2 TL 4 : bind (IJ29231)

medium Nessus Plugin ID 144498
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 AIX host is missing a security patch.

Description ISC BIND is vulnerable to a denial of service, caused by an assertion failure when attempting to verify a truncated response to a TSIG-signed request. By sending a specially-crafted request, a remote authenticated attacker could exploit this vulnerability to cause the server to exit.


Install the appropriate interim fix.
