+Subject: dmidecode: Validate structure completeness before decoding
+
+Ensure that the whole DMI structure fits in the announced table
+length before performing any action on it. Otherwise we might end up
+reading beyond the end of our memory buffer.
+
+This bug was discovered by Lionel Debroux using the AFL fuzzer and
+AddressSanitizer. Its probability is very low, as it requires a DMI
+table corrupted in one of two very specific ways to trigger.
+
+This bug exists since dmidecode version 2.9, although it is hard to
+test because option --from-dump was only introduced in version 2.10.
