An input-validation flaw was found in openstack-neutron, where an authenticated attacker could change the dnsmasq configuration. By crafting extra_dhcp_opts values, the attacker could crash the dnsmasq, change parameters for tenants sharing the same interface, or otherwise alter that daemonβs behavior. This flaw might also be used to trigger a configuration parsing buffer overflow in versions of dnsmasq prior to 2.81. The highest threat from this vulnerability is to system availability, but also threatens data confidentiality and integrity.
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
