Description	This test case implements an unchecked read from a buffer. The buffer is declared as a fixed size buffer on the stack. Untrusted input is not properly sanitized or restricted before being used as an index of the buffer to read. This allows inputs containing non-ascii characters to wrap around to negative indexes and under read the buffer, printing the contents of the memory located before the buffer on the stack to the output stream.
