http://secunia.com/advisories/product/20463/

DESCRIPTION:
Some security issues have been reported in Apertium, which can be
exploited by malicious, local users to perform certain actions with
escalated privileges.

The security issues are caused due to the "apertium-gen-deformat",
"apertium-gen-reformat", and "apertium" scripts using temporary files
in an insecure manner. This can be exploited to delete or overwrite
arbitrary files via symlink attacks.

The security issues are reported in version 3.0.7. Other versions may
also be affected.

SOLUTION:
Restrict local access to trusted users only.
