Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Platform-independent managed code eliminates the need for unchecked native buffer copies that are the root cause of classic buffer overflows.
Out-of-bounds writes that corrupt control flow or inject shellcode are rendered non-executable by the same memory protections.
