A crashed child process will automatically be restarted by the parent process, but an attacker may keep the NSD server occupied restarting child processes by sending it a stream of such packets effectively preventing the NSD server to serve. last seen 2020-06-01 modified 2020-06-02 plugin id 60150 published 2012-07-30 reporter This script is Copyright (C) 2012-2019 and is owned by Tenable, Inc. or an Affiliate thereof. source https://www.tenable.com/plugins/nessus/60150 title FreeBSD : nsd -- Denial of Service (17f369dc-d7e7-11e1-90a2-000c299b62e1) NASL family Fedora Local Security Checks NASL id FEDORA_2012-11203.NASL description Updated upstream releasee for CVE-2012-2979 / VU#517036, our packages were not vulnerable Fix for CVE-2012-2978: NSD denial of service vulnerability from non-standard DNS packet from any host Note that Tenable Network Security has extracted the preceding description block directly from the Fedora security advisory.
