+From bcdd6a55952222ec9829a59348240a4f983b0b56 Mon Sep 17 00:00:00 2001
+From: Peter Jones <pjones@redhat.com>
+Date: Mon, 15 Jun 2020 12:26:01 -0400
+Subject: [PATCH 4/9] calloc: Use calloc() at most places
+
+This modifies most of the places we do some form of:
+
+ X = malloc(Y * Z);
+
+to use calloc(Y, Z) instead.
+
+Among other issues, this fixes:
+ - allocation of integer overflow in grub_png_decode_image_header()
+ reported by Chris Coulson,
+ - allocation of integer overflow in luks_recover_key()
+ reported by Chris Coulson,
+ - allocation of integer overflow in grub_lvm_detect()
+ reported by Chris Coulson.
+
+Fixes: CVE-2020-14308
+
+Upstream-Status: Backport [commit f725fa7cb2ece547c5af01eeeecfe8d95802ed41
+from https://git.savannah.gnu.org/git/grub.git]
+
