-Subject: [PATCH] vboot: Do not use hashed-strings offset
-
-The hashed-strings signature property includes two uint32_t values.
-The first is unneeded as there should never be a start offset into the
-strings region. The second, the size, is needed because the added
-signature node appends to this region.
-
-See tools/image-host.c, where a static 0 value is used for the offset.

-Subject: [PATCH] vboot: Add FIT_SIGNATURE_MAX_SIZE protection
-
-This adds a new config value FIT_SIGNATURE_MAX_SIZE, which controls the
-max size of a FIT header's totalsize field. The field is checked before
-signature checks are applied to protect from reading past the intended
-FIT regions.
-
-This field is not part of the vboot signature so it should be sanity
-checked. If the field is corrupted then the structure or string region
-reads may have unintended behavior, such as reading from device memory.
-A default value of 256MB is set and intended to support most max storage
-sizes.
