SEI CERT C Coding Standard (9)     Page: MEM35-C. Allocate sufficient memory for an object     Page: MEM03-C. Clear sensitive information stored in reusable resources     Page: ARR30-C. Do not form or use out-of-bounds pointers or array subscripts     Page: INT04-C. Enforce limits on integer values originating from tainted sources     Page: INT34-C. Do not shift an expression by a negative number of bits or by greater than or equal to the number of bits that exist in the operand     Page: MSC40-C. Do not violate constraints     Page: ARR38-C. Guarantee that library functions do not form invalid pointers     Page: INT32-C. Ensure that operations on signed integers do not result in overflow     Page: INT18-C. Evaluate integer expressions in a larger size before comparing or assigning to that size
