Publish Date: 2021-05-28

Revision: 1.1


The TCP out of band urgent data processing function would invoke a panic function if the pointer to the end of the out of band urgent data points out of the TCP segment's data. If the panic function hadn't a trap invocation removed it will result in an infite loop and therefore a DoS (continuous loop or a device reset).
