The security issues are caused due to the "src/plugins/mupad/bin/tm_mupad_help" and "src/misc/bundle/TeXmacs" scripts incorrectly setting the environment variables LD_LIBRARY_PATH or DYLD_LIBRARY_PATH. This can be exploited to gain escalated privileges by e.g. tricking a user into running the scripts in a directory containing a malicious library. The security issues are reported in version 1.0.7. Other versions may also be affected. SOLUTION: Restrict access to trusted users only. PROVIDED AND/OR DISCOVERED BY: Red Hat credits Raphael Geissert.
