Wind River VxWorks 6.9 and vx7 has a Buffer Overflow in the TCP component (issue 2 of 4). This is an IPNET security vulnerability: TCP Urgent Pointer state confusion caused by a malformed TCP AO option.
The product copies an input buffer to an output buffer without verifying that the size of the input buffer is less than the size of the output buffer, leading to a buffer overflow.
