### Impact `DDFFileParser` and `DefaultDDFFileValidator` (and so `ObjectLoader`) are vulnerable to [XXE Attacks](https://owasp.org/www-community/vulnerabilities/XML_External_Entity_(XXE)_Processing). [DDF file](https://github.com/eclipse-leshan/leshan/wiki/Adding-new-objects#the-lwm2m-model) is a LWM2M format used to store LWM2M object description. Leshan users are impacted only if they parse untrusted DDF files (e.g. if they let external users provide their own model), in that case they MUST upgrade to fixed version. If you parse only trusted DDF file and validate only with trusted xml schema, upgrading is not mandatory. ### Patches This is fixed in **v1.5.0** and **2.0.0-M13**. ### Workarounds No easy way. Eventually writing your own `DDFFileParser`/`DefaultDDFFileValidator` (and so `ObjectLoader`) creating a `DocumentBuilderFactory` with : ```java // For DDFFileParser DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance(); factory.setFeature(XMLConstants.FEATU...

FreeRDP is a free implementation of the Remote Desktop Protocol (RDP), released under the Apache license. In affected versions a missing offset validation may lead to an Out Of Bound Read in the function `gdi_multi_opaque_rect`. In particular there is no code to validate if the value `multi_opaque_rect->numRectangles` is less than 45. Looping through `multi_opaque_rect->`numRectangles without proper boundary checks can lead to Out-of-Bounds Read errors which will likely lead to a crash. This issue has been addressed in versions 2.11.0 and 3.0.0-beta3. Users are advised to upgrade. There are no known workarounds for this vulnerability.
