From redhad bugzilla at $URL:

Multiple (by checking for ATM technology support, checking for Xtables
extension support, checking for setns() system call support, and in
dhcp-client-script example script) insecure temporary file use cases were found
in iproute. A local attacker could use this flaw to conduct symbolic link
attacks (modify or remove files via specially-crafted link names).

this has never really been an issue for Gentoo.  i've specifically made sure to not run the bundled configure script since it has a lot of hardcoded stuff (compiler, flags, paths, etc...).

as for the example script, i don't see this needing to be addressed in the ebuild.  we install it as documentation.
