Description Jan Lieskovsky 2012-02-27 11:57:31 UTC 
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).

Comment 7 Tomas Hoger 2012-03-21 18:56:08 UTC 
This CVE covers insecure temporary files use in configure script, which is only used at package build time and does not affect users using binary packages provided by Red Hat, and the other issue affects example dhcp-client-script script, which is not included in iproute packages in Red Hat Enterprise Linux. These issue hence has not impact of Red Hat Enterprise Linux users.  They were addressed in Fedora and hence fixes will be included in future Red Hat Enterprise Linux versions, but there is no plan to backport fixes to already released versions.

Statement:

These issues only affect a script used during package build and do not affect binary iproute packages shipped with Red Hat Enterprise Linux. Therefore, they are not planned to be addressed in iproute packages in Red Hat Enterprise Linux 5 and 6, they are only planned to be addressed in the future Red Hat Enterprise Linux versions.
