An issue was discovered in tcp_pulloutofband() in tcp_in.c in HCC embedded InterNiche 4.0.1. The TCP out-of-band urgent-data processing function invokes a panic function if the pointer to the end of the out-of-band data points outside of the TCP segments data. If the panic function hadnt a trap invocation removed, it will enter an infinite loop and therefore cause DoS (continuous loop or a device reset).

Weakness

The product contains an iteration or loop with an exit condition that cannot be reached, i.e., an infinite loop.
