is that it was one way to generate DoS attacks against services parsing
XML unchecked input, you can reproduce this with xmllint command line tool:

thinkpad:~ ->
There is a parser option to disable those kind of sanity checks
thinkpad:~ -> /usr/bin/xmllint --noout --huge Desktop/Download/bugreport.svg
thinkpad:~ ->
this could be 'fixed' in two ways:
- reduce your image size slightly to fit in 10MB uuencoded (inkscape at
saving time could do that kind of checking and warn the user).
- in inkscape code where the XML is loaded add the XML_PARSE_HUGE
option which would disable those checks. It's probably safe in
inkscape code.

Another option might be to switch the background image type from tiff which is huge to an equivalent lossless format but compressed like gif or png, Daniel inkscape-0.48.3.1-2.fc18 has been submitted as an update for Fedora 18. https://admin.fedoraproject.org/updates/inkscape-0.48.3.1-2.fc18 inkscape-0.48.3.1-2.fc17 has been submitted as an update for Fedora 17. https://admin.fedoraproject.org/updates/inkscape-0.48.3.1-2.fc17 Package inkscape-0.48.3.1-2.fc18: * should fix your issue, * was pushed to the Fedora 18 testing repository, * should be available at your local mirror within two days. Update it with: # su -c 'yum update --enablerepo=updates-testing inkscape-0.48.3.1-2.fc18' as soon as you are able to. Please go to the following url: https://admin.fedoraproject.org/updates/FEDORA-2012-17442/inkscape-0.48.3.1-2.fc18 then log in and leave karma (feedback). I just looked at inkscape-0.48.3.1-hugexml.patch and yes that looks exactly the right fix, thanks for the fast reaction, let's make sure the patch is pushed upstream (they use bazaar, which i'm not used to, so didn't checked myself) Daniel No worries, it's from upstream. Great guys, that was fast. I can't test it at the moment, but I believe it should do it. What a satisfying bug reporting experience! :) inkscape-0.48.3.1-2.fc18 has been pushed to the Fedora 18 stable repository. If problems still persist, please make note of it in this bug report. |
Description of problem: When trying to open a file that I created in inkscape on an Ubuntu system in inkscape svg format failes to open in Fedora with an out of memory error message (see below). After removing this element with a text editor the file opens, obviously it was a large background bitmap. Version-Release number of selected component (if applicable): Fedora 17 inkscape.x86_64 0.48.3.1-1.fc17 How reproducible: Try to open specific file in inkscape svg format. Example attached. Actual results: Window "Failed to load the requested file /home/.../asilomar.svg" inkscape opens with empty 'New document 1'. Command line: >> $ inkscape asilomar.svg asilomar.svg:2143: parser error : internal error 8AIAVESAoAYAhoGAOMoAqsXP0HuuQ+uIcMyu8HqHiHyHKHhnyHDQIwGk136hjmLlya2Kko wJUhYH33/ ^ asilomar.svg:2143: error: xmlSAX2Characters: huge text node: out of memory id="flowPara3740" /></flowRoot> <image ^ asilomar.svg:2143: parser error : Extra content at the end of the document id="flowPara3740" /></flowRoot> <image ^ -- cut The file shows around the specified line >> <flowRoot style="font-size:40px;font-style:normal;font-weight:normal;fill:#000000;fill-opacity:1;stroke:none;font-family:Bitstream Vera Sans" id="flowRoot3734" xml:space="preserve"><flowRegion id="flowRegion3736"><rect y="586.6864" x="201.74588" height="61.451332" width="67.248627" id="rect3738" /></flowRegion><flowPara id="flowPara3740" /></flowRoot> <image xlink:href="data:image/tiff;base64,<binarydatagoesonforever>....... -- cut Expected results: File opens and is editable.
