From ae3de0d8caf1822da076b2cc947ea89a0b560e05 Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Mon, 31 Oct 2016 10:21:09 -0600 Subject: [PATCH] image: Protect against overflow in unknown_msg() Coverity complains that this can overflow. If we later increase the size of one of the strings in the table, it could happen. Adjust the code to protect against this.
