Write or buffer overflow on compile-time allocated memory. See the code snippet as follows:
/* test case 2 : out-of-bounds : write overflow [on compile-time memory] */static void write_overflow_compilemem(void){ int i, arr[5], tmp[8]; for (i=0; i<=5; i++) { arr[i] = 100; /* Bug: 'arr' overflows on i==5, overwriting part of the 'tmp' variable - a stack overflow! */ }}
This has caused a stack overflow (also referred to as a stack smashing or buffer overflow (BOF)) bug; it's a serious class of vulnerability that attackers have successfully exploited many a time, starting with the Morris Worm virus back in 1988!

Very interestingly, ...
