openstack-neutron: incorrect validation of port settings in iptables security group driver

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...

CVE-2019-11331

Network Time Protocol NTP, as specified in RFC 5905, uses port 123 even for modes where a fixed port number is not required, which makes it easier for remote attackers to conduct off-path attacks. Mitigation On Red Hat Enterprise Linux 6 and later, switching from ntp to chrony is recommended. Amo...

The vulnerability of the iptables security group driver of the Neutron SDN-platform for OpenStack, related to incorrect handling of security group configurations, allows attackers to circumvent established security policy rules.

The vulnerability of the iptables security group driver of the Neutron SDN-platform for the OpenStack platform is related to incorrect handling of security group configurations. Exploiting this vulnerability allows a malicious actor to circumvent established security policies by blocking further...

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...
