-Subject: [PATCH] migration: fix parameter validation on ram load
-
-During migration, the values read from migration stream during ram load
-are not validated. Especially offset in host_from_stream_offset() and
-also the length of the writes in the callers of said function.
-
-To fix this, we need to make sure that the [offset, offset + length]
-range fits into one of the allocated memory regions.
-
-Validating addr < len should be sufficient since data seems to always be
-managed in TARGET_PAGE_SIZE chunks.
-
-Fixes: CVE-2014-7840
-
-Upstream-Status: Backport
-
-Note: follow-up patches add extra checks on each block->host access.
