gEDA: Insecure temporary file creation

Background

gEDA is an Electronic Design Automation tool used for electrical circuit design.

Description

Dmitry E. Oboukhov reported an insecure temporary file usage within the sch2eaglepos.sh script.

Impact

A local attacker could perform symlink attacks to overwrite arbitrary files with the privileges of the user running the application.

Workaround

There is no known workaround at this time.

Resolution

All gEDA users should upgrade to the latest version:

 # emerge --sync
 # emerge --ask --oneshot --verbose ">=sci-electronics/geda-1.4.0-r1"
