Description:
Gregory Duchemin has reported a vulnerability in D-Link DI-614+, which can be exploited by malicious people to cause a DoS (Denial of Service).
The vulnerability is reportedly caused due to a signedness error within the DHCP service when processing certain DHCP options. This can be exploited by sending a DHCP request with an overly large value in the "LEASETIME" option, which causes it to be interpreted as a negative value.
Successful exploitation consumes all available leases for a much longer time (13+ years) than specified by an administrator.
The vulnerability has been reported in firmware release 2.30 for Revision A. Firmware releases prior to 3.41 B5 for Revision B may also be affected.
