4Subject: [PATCH] Detect invalid length field in debug frame FDE header.
5
6GDB was failing to catch cases where a corrupt ELF or core file
7contained an invalid length value in a Dwarf debug frame FDE header.
8It was checking for buffer overflow but not cases where the length was
9negative or caused pointer wrap-around.
10
11In addition to the additional validity check, this patch cleans up the
12multiple signed/unsigned conversions on the length field so that an
13unsigned representation is used consistently throughout.
14
15This patch fixes CVE-2017-9778 and PR gdb/21600.
