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