A crafted NTFS\nimage with truncated run data in an MFT attribute triggers an OOB heap\nread of up to 15 bytes when the filesystem is mounted.\n\nAdd boundary checks before each run_unpack_s64() call to ensure the\ndeclared field size does not exceed the remaining buffer.\n\nFound by fuzzing with a source-patched harness (LibAFL + QEMU)."
