Last modified
CVE-2017-14339 is a vulnerability of currently unknown severity. 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.. EPSS estimates a 2.53% chance of exploitation in the next 30 days.
