Vendor comments

  • Red HatRed Hat is aware of this issue and is tracking it via the following bug: https://bugzilla.redhat.com/CVE-2010-0437. This issue did not affect the versions of Linux kernel as shipped with Red Hat Enterprise Linux 3 and 4, as they do not include support for Optimistic Duplicate Address Detection (DAD) in IPv6. This was addressed in Red Hat Enterprise Linux 5 via https://rhn.redhat.com/errata/RHSA-2010-9419.html. A future update in Red Hat Enterprise MRG may address this flaw.
