CVSS: 7.1EPSS: 0%CPEs: 8EXPL: 0CVE-2023-5366 – Openvswitch don't match packets on nd_target field
https://notcve.org/view.php?id=CVE-2023-5366
A flaw was found in Open vSwitch that allows ICMPv6 Neighbor Advertisement packets between virtual machines to bypass OpenFlow rules. This issue may allow a local attacker to create specially crafted packets with a modified or spoofed target IP address field that can redirect ICMPv6 traffic to arbitrary IP addresses. Se encontró una falla en Open vSwitch que permite que los paquetes de anuncios de vecinos ICMPv6 entre máquinas virtuales omitan las reglas de OpenFlow. Este problema puede permitir que un atacante local cree paquetes especialmente manipulados con un campo de dirección IP de destino modificado o falsificado que puede redirigir el tráfico ICMPv6 a direcciones IP arbitrarias. • http://www.openwall.com/lists/oss-security/2024/02/08/4 https://access.redhat.com/security/cve/CVE-2023-5366 https://bugzilla.redhat.com/show_bug.cgi?id=2006347 https://lists.debian.org/debian-lts-announce/2024/02/msg00004.html https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/LFZADABUDOFI2KZIRQBYFZCIKH55RGY3 https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/VYYUBF6OW2JG7VOFEOROHXGSJCTES3QO • CWE-345: Insufficient Verification of Data Authenticity •

A flaw was found in Open Virtual Network where the service monitor MAC does not properly rate limit. This issue could allow an attacker to cause a denial of service, including on deployments with CoPP enabled and properly configured. Se encontró una falla en Open Virtual Network donde el monitor de servicio MAC no califica correctamente el límite. Este problema podría permitir que un atacante provoque una denegación de servicio, incluso en implementaciones con CoPP habilitado y configurado correctamente. • https://access.redhat.com/security/cve/CVE-2023-3153 https://bugzilla.redhat.com/show_bug.cgi?id=2213279 https://github.com/ovn-org/ovn/commit/9a3f7ed905e525ebdcb14541e775211cbb0203bd https://github.com/ovn-org/ovn/issues/198 https://mail.openvswitch.org/pipermail/ovs-announce/2023-August/000327.html https://mail.openvswitch.org/pipermail/ovs-dev/2023-August/407553.html • CWE-400: Uncontrolled Resource Consumption CWE-770: Allocation of Resources Without Limits or Throttling •
CVSS: 8.2EPSS: 0%CPEs: 16EXPL: 0CVE-2023-1668 – openvswitch: ip proto 0 triggers incorrect handling
https://notcve.org/view.php?id=CVE-2023-1668
A flaw was found in openvswitch (OVS). When processing an IP packet with protocol 0, OVS will install the datapath flow without the action modifying the IP header. This issue results (for both kernel and userspace datapath) in installing a datapath flow matching all IP protocols (nw_proto is wildcarded) for this flow, but with an incorrect action, possibly causing incorrect handling of other IP packets with a != 0 IP protocol that matches this dp flow. • https://bugzilla.redhat.com/show_bug.cgi?id=2137666 https://lists.debian.org/debian-lts-announce/2023/05/msg00000.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/V2GUNS3WSJG4TUDKZ5L7FXGJMVOD6EJZ https://security.gentoo.org/glsa/202311-16 https://www.debian.org/security/2023/dsa-5387 https://www.openwall.com/lists/oss-security/2023/04/06/1 https://access.redhat.com/security/cve/CVE-2023-1668 • CWE-670: Always-Incorrect Control Flow Implementation •
