Subject: CVE request: rawstudio: Insecure use of temporary file


The following was reported:
The function "rs_filter_graph" located in file
./librawstudio/rs-filter.c contains the following code:

         g_string_append_printf(str, "}\n");
         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

Can CVE be assigned to this?
