Overview

imgtool is a MCUboot's image signing and key management

Affected versions of this package are vulnerable to Improper Validation of Integrity Check Value in image_validate.c, when boot record functionality is enabled. An attacker can inject dependencies or boot record fields into a TLV entry which should be treated as protected. This allows the rejection of valid images and addition of fabricated properties to an image.
