CVE-2021-41616: Apache ddlutils 1.0 readobject vulnerability

[Bryan Pendleton <bpendleton () apache org>]

Description:

Apache DB DdlUtils 1.0 included a BinaryObjectsHelper that was intended for use when migrating database data with a SQL 
data type of BINARY, VARBINARY, LONGVARBINARY, or BLOB between databases using the ddlutils features. The 
BinaryObjectsHelper  class was insecure and used ObjectInputStream.readObject without validating that the input data 
was safe to deserialize.

Please note that DdlUtils is no longer being actively developed. To address the insecurity of the BinaryObjectHelper 
class, the following changes to DdlUtils have been made: (1) BinaryObjectsHelper.java has been deleted from the 
DdlUtils source repository and the DdlUtils feature of propagating data of SQL binary types is therefore no longer 
present in DdlUtils; (2) The ddlutils-1.0 release has been removed from the Apache Release Distribution Infrastructure; 
(3) The DdlUtils web site has been updated to indicate that DdlUtils is now available only as source code, not as a 
packaged release.
