CVE-2014-4978
First published: Tue Jul 15 2014(Updated: )
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: /tmp/rs-filter-graph.png /tmp/rs-filter-graph 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
