Tenda i29 sysScheduleRebootSet method buffer overflow vulnerability

The Tenda i29 is a wireless router from the Chinese company Tenda. The Tenda i29 suffers from a buffer overflow vulnerability that originates from the rebootTime parameter of the sysScheduleRebootSet method failing to correctly validate the length of the input data, which can be exploited by a remote attacker to execute arbitrary code on the system or lead to a denial of service attack.
