From d6d21dfdd305bf94300df13ff472141d3411ea17 Mon Sep 17 00:00:00 2001 From: Darren Jenkins Date: Sun, 26 Mar 2006 01:37:34 -0800 Subject: [PATCH] fix array overrun in efi.c Coverity found an over-run @ line 364 of efi.c This is due to the loop checking the size correctly, then adding a '\0' after possibly hitting the end of the array. Ensure the loop exits with one space left in the array.
