+Subject: [PATCH] dvi: Mitigate command injection attacks by quoting filename
+
+With commit 1fcca0b8041de0d6074d7e17fba174da36c65f99 came a DVI backend.
+It exports to PDF via the dvipdfm tool.
+It calls that tool with the filename of the currently loaded document.
+If that filename is cleverly crafted, it can escape the currently
+used manual quoting of the filename.  Instead of manually quoting the
+filename, we use g_shell_quote.
