Fortify issues

[tchaitrali]

Following fortify issues are reported on these xsd files. Are there any plans to fix these issues?

• Weak XML Schema: Lax Processing
• Weak XML Schema: Type Any
• Weak XML Schema: Unbounded Occurrences
• Weak XML Schema: Undefined Namespace

I'm sorry, but what exactly are "fortify" issues, i.e., whence do these complaints arise?

The lax processing, any type allowances and unbounded occurrence instances were all quite intentionally designed into the OVAL schemas. And they are also all quite irreversible without breaking backwards-compatibility.

I am curious about the "undefined namespace". I believe all the namespaces are well-defined.

Thanks for the reply.
Fortify issues - When we used Fortify Software Security Center, it gave above list of issues for xsd files.
Please refer following for "Undefined Namespace":

The "undefined namespace" issue is a side-effect of allowing the use of custom metadata schemas. This is a feature of OVAL as well.

Using a tool such as Fortify to perform static analysis can be very useful, but you are still left with the burden of having to understand and interpret its output. If you do not believe that you can trust the schema-aware XML processor you've chosen to ingest OVAL content directly, you are free to create your own more restrictive schemas and live without the features that you've chosen to eliminate. But the OVAL community has no immediate plans to do so.
