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.

Please use CVE-2012-1088 for these issues (same codebase/same
discoverer/same issue type/same version so merging).
