Delivered patches are:

• 5.2 → 5.2.1
• 5.3.0 / 5.3.1 → 5.3.2

Please consider that use of older versions should be discouraged.

XAdES / ASiC with XAdES / TL-based signature validation

If your DSS integration is using XAdES, ASiC with XAdES, or TL-based signature validation, it is strongly encouraged to upgrade your version.

The patches enforce signature validations against different kinds of attack: XML Signature Wrapping (XSW), XPath injections, Server Side Request Forgeries (SSRF) and XML External Entities (XEE).

While upgrading, be sure that your integration :

• doesn't use Xalan or XercesImpl dependencies
• uses a patched Java version (JDK7u40+, JDK8 or higher)

PAdES

If you use dss-pades, it is also strongly encouraged to upgrade your DSS version, as these releases include a fix of PdfBox to patch vulnerabilities.
