Since the length of the TLV field is defined by the TLV itself it is possible that length record_len in IMAGE_TLV_BOOT_RECORD is reasonably arbitrary.\n\nThe TLV data in the image stored in flash cannot be fully trusted since there is no authentication of the TLV data performed by the mcuboot bootloader. In case of an external SPI flash the tlv data can be easily modified by the attacker as well.\n\nThe value record_len is checked to be not larger than the receiving buffer buf, but not checked if it is smaller than the expected length.\n\nIn case record_len is smaller than sizeof(image_hash) integer underflow will take place resulting in a negative value interpreted as an unsigned value. Once the offset is added to the pointer buff the destination pointer value will overflow and up to 31 bytes of attacker controlled data will be written on the stack out of bounds, resulting in the stack memory corruption and depending on the stack layout can lead to an arbitrary code execution."

          "text": "MCUboot uses a TLV (tag-length-value) structure to represent the meta data associated with an image. The TLVs themselves are divided into two sections, a protected and an unprotected section. The protected TLV entries are included as part of the image signature to avoid tampering. However, the code does not distinguish which TLV entries should be protected or not, so it is possible for an attacker to add unprotected TLV entries that should be protected. Currently, the primary protected TLV entries should be the dependency indication, and the boot record. An injected dependency value would primarily result in an otherwise acceptable image being rejected. A boot record injection could allow fields in a later attestation record to include data not intended, which could cause an image to appear to have properties that it should not have.",
