This vulnerability has been modified since it was last analyzed by the NVD. It is awaiting reanalysis which may result in further changes to the information provided.
net/bridge/netfilter/ebtables.c in the ebtables module in the netfilter framework in the Linux kernel before 2.6.33-rc4 does not require the CAP_NET_ADMIN capability for setting or modifying rules, which allows local users to bypass intended access restrictions and configure arbitrary network-traffic filtering via a modified ebtables application.

Red Hat is aware of this issue and is tracking it via the following bug:
This issue did not affect the version of Linux kernel as shipped with Red Hat Enterprise Linux 3, as it did not include support for
ebtables. This issue was addressed in Red Hat Enterprise Linux 4 and 5 via https://rhn.redhat.com/errata/RHSA-2010-0146.html and https://rhn.redhat.com/errata/RHSA-2010-0147.html respectively. A futur
e update in Red Hat Enterprise MRG may address this flaw.
