    CVE-2017-14339

    Published: 20 Sept 2017Last Modified: 8 Jul 2026

    Summary:

    Details: The DNS packet parser in YADIFA before 2.2.6 does not check for the presence of infinite pointer loops, and thus it is possible to force it to enter an infinite loop. This can cause high CPU usage and makes the server unresponsive.
