I can't build 0.48.4 on EL-5 it needs a newer intltool, is the inkscape 0.46 there affected?

(In reply to comment #2) Hi Jon, > I can't build 0.48.4 on EL-5 it needs a newer intltool, is the inkscape 0.46 > there affected? Yes, it is. I have tried the reproducer from https://bugzilla.redhat.com/show_bug.cgi?id=888249#c1 yesterday and it works on EPEL-5 version too. So we will need some other way how to fix this (backport the isolated patch). Regards, Jan. -- Jan iankko Lieskovsky / Red Hat Security Response Team

I understand what the patch is trying to accomplish, I'm just not sure how to get the allow_net_access option, Inkscape::Preferences *prefs = Inkscape::Preferences::get(); doesn't seem to work in 0.46.

So what do you propose? Discontinue support for inkscape in EPEL-5 and delete it? (not that this flaw would be so critical, it would need to be done. But current limitation not being to able to build new updates might be a problem if / once there is a more urgent inkscape issue found).
Comment 6 Gwyn Ciesla 2012-12-20 10:14:54 EST
No, possibly just simplify the patch to avoid the option check, and just disable network importing at those locations. Thoughts?

(In reply to comment #6) > No, possibly just simplify the patch to avoid the option check, and just > disable network importing at those locations. Thoughts? So divided into coins, what you suggest wrt to: http://bazaar.launchpad.net/~inkscape.dev/inkscape/trunk/revision/11931 is that the patch would use just: 1115 int parse_options = XML_PARSE_RECOVER + XML_PARSE_NOWARNING + XML_PARSE_NOERROR; // do not use XML_PARSE_NOENT ! see bug lp:1025185 at src/ui/dialog/ocaldialogs.cpp and use just: 300 int parse_options = XML_PARSE_HUGE; // do not use XML_PARSE_NOENT ! see bug lp:1025185 and - 305 XML_PARSE_NOENT | XML_PARSE_HUGE); + 311 parse_options); at src/xml/repr-io.cpp, right? (IOW explicitly disable the XML_PARSE_NOENT by default without ability to switch it on again [without custom recompilation], right?)
Comment 8 Gwyn Ciesla 2012-12-20 10:44:21 EST
Pretty much. Will that suffice to fix the flaw?
Comment 9 Jan Lieskovsky 2012-12-20 11:54:32 EST
(In reply to comment #8) > Pretty much. Will that suffice to fix the flaw? Yes, that should fix the problem.
Comment 10 Gwyn Ciesla 2012-12-20 12:57:00 EST
