This error causes the receiver to misinterpret the urgent data's positio...
Astra Linux – Vulnerability in open-iscsi
A 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. It...
