Depending on the type of download and the changes in the firmware image, a reboot of the system may be required. The active firmware slot is then switched from the currently used slot to the slot assigned to the downloaded image. In order to make the downloaded image the active firmware image, it is assigned to slot. A portion of an image is limited by min( Controller Maximum Transfer Size, 512 KB). Depending on the size of the image, this occurs in a single transfer operation or in successive transfers of multiple portions of the image.

All existing image data in the selected slot is overwritten when the update is completed.ĭownload the new firmware image for a selected slot. In order to update the device, a slot is chosen that is writeable and not currently active.

  • Which slot contains the current active firmware image (the running firmware)?.
  • How many slots can hold an update? Some slots are read-only or hold images that must be retained if the ability to revert to a prior image is desired.
    • There are a few considerations in deciding where the firmware update will reside. Gather the firmware slot information to determine where to place the update. Firmware is updated using the IOCTL_SCSI_MINIPORT request containing the associated firmware control data formatted in an SRB. NVMe devices certified for Windows are capable of updating their firmware while the device is in operation. Function commands for getting firmware information, downloading, and activating firmware images are issued to the miniport.

    Tizen - An open source, standards-based software platform for multiple device categories.Blog - Möbius Strip Reverse Engineering.IBM Product Security Incident Response Team.This is helpful so that you can discover the typical mistakes people make in UEFI development, and also so that you won’t make the same mistakes yourself! Nikolaj discovered many serious problems, and I found it educational to read through them.

    The BSP is a set of documentation and EDKII source code that allows a developer to build his own bootable firmware image for the Quark. Galileo is a small computer board comparable to the Arduino family of products, and is targeted to maker and educational customers. For example, it runs the Intel Galileo family of development boards. The Intel Quark is an SoC used in embedded systems applications.

    William Leara of Dell has a new blog post about Nikolaj Schlej’s new blog post analyzing Intel Quark’s BSP:Īnother tip of the cap to Nikolaj Schlej, this time for an interesting article where he examined the Intel Quark Board Support Package (BSP) source code with the static source code analyzer PVS-Studio. There is a translation of that post made by PVS-Studio authors: Intel would like to thank Embedi for reporting CVE-2017-5721 and CVE-2017-5722 and working with us on coordinated disclosure. Intel would like to thank Nikolaj Schlaj for reporting CVE-2017-5700 and CVE-2017-5701 and working with us on coordinated disclosure. Intel highly recommends that users update to the latest version. Dangerous SPI Opcode Protections: Insufficient policy enforcement in system firmware for Intel® NUC systems allows attacker with local or physical access to violate integrity or availability of nonvolatile storage for firmware via specially crafted accesses to nonvolatile storage. Boot Guard Bypass: Incorrect policy enforcement in system firmware for Intel® NUC systems allows attacker with local or physical access to bypass enforcement of integrity protections via manipulation of firmware storage.

    SMM Privilege Elevation: Insufficient input validation in system firmware for Intel® NUC systems allows local attacker to execute arbitrary code via manipulation of memory. SPI Write Protection Bypass: Insecure platform configuration in system firmare for NUC7i3BNK, NUC7i3BNH, NUC7i5BNK, NUC7i5BNH, NUC7i7BNH versions BN0049 and below allows an attacker with physical presence to run arbitrary code via unauthorized firmware modification during BIOS Recovery.

    BIOS Administrator and User password bypass: Insufficient protection of password storage in system firmware for NUC7i3BNK, NUC7i3BNH, NUC7i5BNK, NUC7i5BNH, NUC7i7BNH versions BN0049 and below allows local attacker to bypass Administrator and User passwords via access to password storage. This update improves protection against mitigates multiple vulnerabilities related to security features in Intel® NUC system firmware (BIOS).
