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 •
CVSS: -EPSS: 0%CPEs: 2EXPL: 0CVE-2022-32166 – ovs - buffer over-read
https://notcve.org/view.php?id=CVE-2022-32166
In ovs versions v0.90.0 through v2.5.0 are vulnerable to heap buffer over-read in flow.c. An unsafe comparison of “minimasks” function could lead access to an unmapped region of memory. This vulnerability is capable of crashing the software, memory modification, and possible remote execution. ovs versiones v0.90.0 hasta v2.5.0, son vulnerables a una lectura excesiva del buffer de la pila en el archivo flow.c. Una comparación no segura de la función "minimasks" podría conllevar a un acceso a una región de memoria no mapeada. Esta vulnerabilidad es capaz de bloquear el software, modificar la memoria y una posible ejecución remota • https://github.com/cloudbase/ovs/commit/2ed6505555cdcb46f9b1f0329d1491b75290fc73 https://lists.debian.org/debian-lts-announce/2022/10/msg00036.html https://www.mend.io/vulnerability-database/CVE-2022-32166 • CWE-125: Out-of-bounds Read •
