+Subject: [PATCH] Detect invalid length field in debug frame FDE header.
+
+GDB was failing to catch cases where a corrupt ELF or core file
+contained an invalid length value in a Dwarf debug frame FDE header.
+It was checking for buffer overflow but not cases where the length was
+negative or caused pointer wrap-around.
+
+In addition to the additional validity check, this patch cleans up the
+multiple signed/unsigned conversions on the length field so that an
+unsigned representation is used consistently throughout.
+
+This patch fixes CVE-2017-9778 and PR gdb/21600.

+
+	* dwarf2-frame.c (read_initial_length): Be consistent about using
+	unsigned representation of length.
+	(decode_frame_entry_1): Likewise.  Check for wraparound of
+	end pointer as well as buffer overflow.
