Name of the Vulnerable Software and Affected Versions scilab-bin version 4.1.2

Description The issue allows local users to overwrite arbitrary files via a symlink attack on various temporary files, including /tmp/SciLink#####1, /tmp/SciLink#####2, /tmp/SciLink#####3, /tmp/*.#####, /tmp/*.#####.res, /tmp/*.#####.err, and /tmp/*.#####.diff. This is related to the scilink, scidoc, and scidem scripts.

Recommendations For scilab-bin version 4.1.2, consider restricting access to the temporary files in /tmp to prevent a symlink attack until a patch is available. As a temporary workaround, avoid using the scilink, scidoc, and scidem scripts that create these temporary files. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
