From 1d88a99d1b9175c41f015631311fd9e5966eb997 Mon Sep 17 00:00:00 2001 From: Masahiro Yamada Date: Fri, 27 Oct 2017 13:25:21 +0900 Subject: tools: image: fix "algo" property of public key for verified boot The "algo_name" points to a property in a blob being edited. The pointer becomes stale when fit_image_write_sig() inserts signatures. Then crypto->add_verify_data() writes wrong data to the public key destination.
