4Subject: [PATCH] gettext: Integer overflow leads to heap OOB write or read
5
6Calculation of ctx->grub_gettext_msg_list size in grub_mofile_open() may
7overflow leading to subsequent OOB write or read. This patch fixes the
8issue by replacing grub_zalloc() and explicit multiplication with
9grub_calloc() which does the same thing in safe manner.
