Unreasonable Size Argument

Compass/ROSE

could check violations of this rule by examining the size expression to malloc() or memcpy() functions. Specifically, the size argument should be bounded by 0, SIZE_MAX, and, unless it is a variable of type size_t or rsize_t, it should be bounds-checked before the malloc() call. If the argument is of the expression a*b, then an appropriate check is

SIZECHECK

Can find instances where string length is miscalculated (length calculated may be one less than intended) for memory allocation purposes. Coverity Prevent cannot discover all violations of this rule, so further verification is necessary

Finds memory allocations that are assigned to a pointer that reference objects larger than the allocated block
