The following was reported:
The function "rs_filter_graph" located in file ./librawstudio/rs-filter.c contains the following code:
g_file_set_contents("/tmp/rs-filter-graph", str->str, str->len, NULL);
ignore = system("dot -Tpng >/tmp/rs-filter-graph.png </tmp/rs-filter-graph");
ignore = system("gnome-open /tmp/rs-filter-graph.png");
This code makes insecure use of two temporary files:
This allows the truncation of arbitrary files which are owned by the user running
rawstudio - for example:
ln -s ~/.important /tmp/rs-filter-graph
ln -s /etc/shadow /tmp/rs-filter-graph.png

MITRE assigned CVE-2014-4978 to this issue.
Upstream seems dead, last commit is on February, maybe it's time to retire the package.
This is upstream - not dead :)
Please note that this function can not be called by end users without modifying Rawstudio source. We disabled it in march 2011.
Fix is here for future references:
- but IMO the fix is not very important. End users cannot call this without adding a "FilterGraph" menuitem to ui.xml.
rawstudio-2.1-0.1.20150511git983bda1.fc22 has been pushed to the Fedora 22 stable repository. If problems still persist, please make note of it in this bug report.
