Buffer overrun 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, array size: `[5,5]`,
|
|
offset: `[3,3]`.
|
|
|
|
* `L2`: Less faithful report than `L1`, when it *may* be unsafe. For example, array size:`[5,5]`,
|
|
offset: `[0,5]`. Note that the offset may be a safe value in the real execution, i.e. 0, 1, 2,
|
|
3, 4.
|
|
|
|
* `L5`: The least faithful report, when there is an interval top. For example, array size:
|
|
`[5,5]`, offset: `[-oo,+oo]`.
|
|
|
|
* `L4`: More faithful report than `L5`, when there is an infinity value. For example, array size:
|
|
`[5,5]`, offset: `[0, +oo]`.
|
|
|
|
* `L3`: The reports that are not included in the above cases.
|
|
|
|
* `S2`: An array access is unsafe by symbolic values. For example, array size: `[n,n]`, offset
|
|
`[n,+oo]`.
|
|
|
|
* `U5`: An array access is unsafe by unknown values, which are usually from unknown function
|
|
calls.
