VUL-0: CVE-2015-8914: openstack-neutron: Neutron IPTables firewall anti-spoof protection bypass
Last modified: 2017-08-04 08:58:03 UTC
CVE-2015-8914 Title: Neutron IPTables firewall anti-spoof protection bypass independently reported vulnerabilities in Neutron anti-spoof protection. By forging DHCP discovery messages or non-IP traffic, such as ARP or ICMPv6, an instance may spoof IP or MAC source addresses on attached networks resulting in denial of services and/or traffic interception. Moreover when L2population isn't used, other tenants attached to a shared network are also vulnerable. Neutron setups using the IPTables firewall driver are affected. The dhcp fix has been included in the 8.0.0 release and this request probably needs more than one CVE. https://bugs.launchpad.net/neutron/+bug/1502933/comments/21 Just to be clear, the ICMPv6 source address spoof isn't addressed by bug 1558658 patch (I39dc0e23fc118ede19ef2d986b29fc5a8e48ff78). Since both issues abuse the same fundamental flaw, it seems like a good opportunity to bundle both fix in a single advisory. However, because we need different patch, this will likely requires 2 different CVE numbers... https://bugs.launchpad.net/bugs/1502933 (ICMPv6 source address spoofing) Use CVE-2015-8914.
