An insecure temporary file usage has been reported in Scilab, allowing for symlink attacks.
|Package||sci-mathematics/scilab on all architectures|
|Affected versions||< 4.1.2-r1|
|Unaffected versions||>= 4.1.2-r1|
Scilab is a scientific software package for numerical computations.
Dmitry E. Oboukhov reported an insecure temporary file usage within the scilink, scidoc and scidem scripts.
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 Scilab users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=sci-mathematics/scilab-4.1.2-r1"
