Why is this an issue?
Pointer and unmanaged function pointer types such as IntPtr, UIntPtr, int* etc. are used to access unmanaged
memory, usually in order to use C or C++ libraries. If such a pointer is not secured by making it private, internal or
readonly, it can lead to a vulnerability allowing access to arbitrary locations.
Noncompliant code example
using System;
namespace MyLibrary
{
public class MyClass
{
public IntPtr myPointer; // Noncompliant
protected UIntPtr myOtherPointer; // Noncompliant
}
}
Compliant solution
using System;
namespace MyLibrary
{
public class MyClass
{
private IntPtr myPointer;
protected readonly UIntPtr myOtherPointer;
}
}
