poppler security fix version 0.5.4-4.4.el5_3.9 makes evince incapable in showing pdf documents generated by Xerox WorkCentre scanner.

previous version of poppler could show documents just fine.

Please fix this regression.

btw. fc10 poppler can handle these same files just fine.

Im thinking the CVE-2009-0146.CVE-2009-0147.CVE-2009-0166.patch was incomplete and I have created an additional patch based off poppler-0.5.4-8 in order to fix this bug.

Comment 10 Tuomo Soini 2009-08-18 07:47:37 EDT
Your additional patch doesn't apply rhel-5.3 poppler so I couldn't test it.
Comment 11 Adam Stokes 2009-08-18 09:27:03 EDT
If I got you some test packages would you be willing to test it?

Comment 12 Tuomo Soini 2009-08-18 10:29:39 EDT
Yes, of course. That's why I commented.
Comment 13 Adam Stokes 2009-08-18 10:37:28 EDT

Here you go:


I've provided the srpm as well if you wish to make anymore modifications to the patch or if you need to build for another arch.

Comment 16 Tuomo Soini 2009-08-20 01:45:57 EDT
Seems like test packages really do fix this issue. I was able to open my scanned documents without problems.
Comment 17 Adam Stokes 2009-08-20 09:40:57 EDT
Sounds good, I'll be in contact with the engineer to get this properly ack'd so it can make it into an update.

Comment 19 Christopher Aillon 2009-09-09 18:37:17 EDT
Marek, since you did the last few updates, can you look into this?

a patch fixing reading of arithmetically encoded JBIG2 images with unknown length

The problem here is that poppler doesn't read arithmetically encoded JBIG2 images
correctly. The pdf has generic region segment with length 0xffffffff which signals that actual length is not known and that there is a termination sequence at the end of the segment + 4 bytes long row count. The row count is not read as a part of this segment and poppler handles these 4 bytes as a beginning of a new segment. But the new segment has only 4 bytes, so, further reading raises EOF error.

Attached patch fixes this.

Comment 23 Tuomo Soini 2009-09-18 12:34:10 EDT
Marek, yes your fix seen to solve this problem. I applied that patch over latest rhel poppler and not it works for me.
