Vulnerability CVE-2015-8914

Vulnerability Name:

CVE-2015-8914 (CCN-113943)

Assigned:

2016-06-10

Published:

2016-06-10

Updated:

Summary:

The IPTables firewall in OpenStack Neutron before 7.0.4 and 8.0.0 through 8.1.0 allows remote attackers to bypass an intended ICMPv6-spoofing protection mechanism and consequently cause a denial of service or intercept network traffic via a link-local source address.
