Hallo everybody,
i'm using PDFbox to check if a PDF file contains malicious scripts. I'm using the
PDF/A-1a validation to check the file. Since i'm searching only for potential damaging
code and not for a true PDF/A-1a standard accompliance, is it enough to consider 1.x.x,
6.x.x and 7.x.x errors as "true" errors? Below category description:
Category Description
1[.y[.z]] Syntax Error
2[.y[.z]] Graphic Error
3[.y[.z]] Font Error
4[.y[.z]] Transparency Error
5[.y[.z]] Annotation Error
6[.y[.z]] Action Error
7[.y[.z]] Metadata Error
Unclear what you're asking. Are you seeking to detect files with
javascript? If so, I'd rather build something something from scratch,
i.e. read the PDF specification and see where JS is used. Maybe compare
with the preflight source code to check that you didn't miss something.
