+Subject: [PATCH] Check file size before getting section contents
+
+Don't check the section size in bfd_get_full_section_contents since
+the size of a decompressed section may be larger than the file size.
+Instead, check file size in _bfd_generic_get_section_contents.
+
+        PR binutils/21665
+        * compress.c (bfd_get_full_section_contents): Don't check the
+        file size here.
+        * libbfd.c (_bfd_generic_get_section_contents): Check for and
+        reject a section whoes size + offset is greater than the size
+        of the entire file.
+        (_bfd_generic_get_section_contents_in_window): Likewise.
