+Subject: [PATCH] Fix string format vulnerability
+
+If the message in g_log_structured itself
+contained format sequences like %d or %n they
+were applied again, leading to leaked stack contents
+and possibly memory corruption. It can be triggered
+e.g. by a volume label containing format sequences.
+
+Print the message argument itself into a "%s" string
+to avoid intepreting format sequences.
