Description
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D

Dmitry E. Oboukhov reported an insecure temporary file usage within the
scilink, scidoc and scidem scripts.

Impact
=3D=3D=3D=3D=3D=3D

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

Workaround
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D

There is no known workaround at this time.

Resolution
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D

All Scilab users should upgrade to the latest version:

 # emerge --sync
 # emerge --ask --oneshot --verbose ">=3Dsci-mathematics/scilab-4.1.2-r1"=
