CVE Request -- Multiple instances of insecure temporary file use
From: Jan Lieskovsky <jlieskov () redhat com>
Date: Mon, 27 Feb 2012 13:07:59 +0100

Hello Kurt, Steve, vendors,

  multiple instances (by checking for ATM technology support, checking for Xtables
extension support, checking for setns() system call support, and in
dhcp-client-script example script) of insecure temporary file use 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).

Could you allocate a CVE identifier for this?

Thank you && Regards, Jan.
