pdftops pdf security

[Ryan Donnelly]

Hi,

I'm currently looking into an issue with our pdftops implementation on CUPS 1.4.6.  We're using xpdf 3.02pl5 as our backend.  The issue we're seeing appears to stem from a security issue with certain PDFs.  When we use pdftops by itself, we get:


/usr/bin/pdftops ref.pdf
Error: No display font for 'Courier'
Error: No display font for 'Courier-Bold'
Error: No display font for 'Courier-BoldOblique'
Error: No display font for 'Courier-Oblique'
Error: No display font for 'Helvetica'
Error: No display font for 'Helvetica-Bold'
Error: No display font for 'Helvetica-BoldOblique'
Error: No display font for 'Helvetica-Oblique'
Error: No display font for 'Symbol'
Error: No display font for 'Times-Bold'
Error: No display font for 'Times-BoldItalic'
Error: No display font for 'Times-Italic'
Error: No display font for 'Times-Roman'
Error: No display font for 'ZapfDingbats'


It's my understanding that the font issues are acceptable.  A valid PS file is created and it prints just fine.  When I use the CUPS filter, I get:


/usr/lib/cups/filter/pdftops 1 2 3 4 5 ref.pdf > ref.ps
DEBUG: pdftops - level = 2, width = 595, length = 792
DEBUG: Setting paper dimensions to 595x792!
Error: PDF version 1.7 -- xpdf supports version 1.5 (continuing anyway)
Error: Unsupported version/revision (4/4) of Standard security handler
Error: Incorrect password
Error: Unable to print this document.


Is this consistent with what I should be seeing?  Or could this be related to our issue?  Any help or insight would be appreciated.  I can supply more info if needed.
