    Summary: Open-iSCSI security update

    Details: The Open-iSCSI project is a high-performance, transport independent, multi-platform implementation of RFC3720 iSCSI. Security Fix(es): An issue was discovered in uIP 1.0, as used in Contiki 3.0 and other products. When the Urgent flag is set in a TCP packet, and the stack is configured to ignore the urgent data, the stack attempts to use the value of the Urgent pointer bytes to separate the Urgent data from the normal data, by calculating the offset at which the normal data should be present in the global buffer. However, the length of this offset is not checked; therefore, for large values of the Urgent pointer bytes, the data pointer can point to memory that is way beyond the data buffer in uip_process in uip.c.(CVE-2020-17437)
