Integer overflows reports fall into several "buckets" corresponding to the expected precision of the report. The higher the number, the more likely it is to be a false positive.
-
L1: The most faithful report, when it must be unsafe. For example,[2147483647,2147483647] + [1,1]in 32-bit signed integer type. -
L2: Less faithful report thanL1, when it may be unsafe. For example,[2147483647,2147483647] + [0,1]in 32-bit signed integer type. Note that the integer of RHS can be 0, which is safe. -
L5: The reports that are not included in the above cases. -
U5: A binary integer operation is unsafe by unknown values, which are usually from unknown function calls.
