gEDA is an Electronic Design Automation tool used for electrical circuit design.
Dmitry E. Oboukhov reported an insecure temporary file usage within the sch2eaglepos.sh script.
A local attacker could perform symlink attacks to overwrite arbitrary files with the privileges of the user running the application.
There is no known workaround at this time.
All gEDA users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=sci-electronics/geda-1.4.0-r1"
