+Subject: main: fix heap overflow in dbus-launch wrapping
+
+I have discovered a heap overflow with the help of an address sanitizer.
+
+The require_dbus_session() function has this code:
+
+        new_argv = g_malloc (argc + 3 * sizeof (*argv));
+
+The intention is to allocate space for (argc + 3) pointers. However obviously a
+parenthesis is missing, therefore only argc bytes + 3 * pointer size gets
+allocated, which is insufficient space. This leads to invalid memory writes.
+
+The fix is trivial: Parentheses around argc + 3.
