4 | Caution: This module requires additional review when modified.\r | |
5 | This module will have external input - capsule image.\r | |
6 | This external input must be validated carefully to avoid security issue like\r | |
7 | buffer overflow, integer overflow.\r | |
8 | \r | |
9 | FmpSetImage() will receive untrusted input and do basic validation.\r | |

375 | This function updates the hardware with the new firmware image.\r | |
376 | This function returns EFI_UNSUPPORTED if the firmware image is not updatable.\r | |

379 | - Validate the image authentication if image has attribute\r | |
380 | IMAGE_ATTRIBUTE_AUTHENTICATION_REQUIRED. The function returns\r | |
381 | EFI_SECURITY_VIOLATION if the validation fails.\r | |
382 | - Validate the image is a supported image for this device. The function returns EFI_ABORTED if\r | |

384 | why the image is not a supported image.\r | |

386 | VendorCode data validation. VendorCode data is ignored or considered invalid if image\r | |
387 | validation failed. The function returns EFI_ABORTED if the data is invalid.\r | |
388 | \r | |
389 | VendorCode enables vendor to implement vendor-specific firmware image update policy. Null if\r | |

391 | a policy to allow an option to force a firmware image update when the abort reason is due to the new\r | |
392 | firmware image version is older than the current firmware image version or bad image checksum.\r | |
393 | Sensitive operations such as those wiping the entire firmware image and render the device to be\r | |
394 | non-functional should be encoded in the image itself rather than passed with the VendorCode.\r | |

397 | \r | |
398 | @param[in] This A pointer to the EFI_FIRMWARE_MANAGEMENT_PROTOCOL instance.\r | |

401 | @param[in] Image Points to the new image.\r | |
402 | @param[in] ImageSize Size of the new image in bytes.\r | |
403 | @param[in] VendorCode This enables vendor to implement vendor-specific firmware image update policy.\r | |
404 | Null indicates the caller did not specify the policy or use the default policy.\r | |
