Firewall Misconfiguration

github.com/containernetworking/plugins contains firewall misconfigurations. The misconfiguration causes the HostPort/portmap rule to take precedence on matching incoming traffic even if there are earlier rules or better fitting rules in the iptables nat chains...

Denial Of Service (DoS)

kernel is vulnerable to privilege escalation. A use-after-free in the tcpmssmanglepacket function in net/netfilter/xtTCPMSS.c allows remote attackers to cause a denial of service by leveraging the presence of xtTCPMSS in an iptables action. The successful exploit of the vulnerable can potentially...

CVE-2019-9735

A validation flaw was discovered in the iptables firewall module in OpenStack Neutron. By setting a destination port in a security group rule, along with a protocol that does not support that option for example, VRRP, an authenticated user could block further application of security group rules f...

Debian DSA-4409-1 : neutron - security update

Erik Olof Gunnar Andersson discovered that incorrect validation of port settings in the iptables security group driver of Neutron, the OpenStack virtual network service, could result in denial of service in a multi tenant setup. C Tenable Network Security, Inc. The descriptive text and package...

Security Rules Bypass

neutron is vulnerable to bypass of security rules. The vulnerability exists because it does not prevent addition of invalid rules in the iptables firewall module, such as setting a destination port for Virtual Router Redundancy Protocol VRRP, resulting in an error that prevents computation of...
