CVE-2017-2889 (GCVE-0-2017-2889)

Vulnerability from cvelistv5 – Published: 2017-11-07 16:00 – Updated: 2024-09-17 01:25

Summary

An exploitable Denial of Service vulnerability exists in the API daemon of Circle with Disney running firmware 2.0.1. A large amount of simultaneous TCP connections causes the APID daemon to repeatedly fork, causing the daemon to run out of memory and trigger a device reboot. An attacker needs network connectivity to the device to trigger this vulnerability.
