+Subject: [PATCH 16/40] CVE-2014-0210: unvalidated length fields in
+ fs_read_list() from xorg/lib/libXfont commit
+ 5fa73ac18474be3032ee7af9c6e29deab163ea39
+
+fs_read_list() parses a reply from the font server.  The reply
+contains a list of strings with embedded length fields, none of
+which are validated. This can cause out of bound reads when looping
+over the strings in the reply.
