https://notcve.org/view.php?id=CVE-2023-3637
25 Jul 2023 — An uncontrolled resource consumption flaw was found in openstack-neutron. This flaw allows a remote authenticated user to query a list of security groups for an invalid project. This issue creates resources that are unconstrained by the user's quota. If a malicious user were to submit a significant number of requests, this could lead to a denial of service. OpenStack Networking is a virtual network service for OpenStack. • https://access.redhat.com/errata/RHSA-2023:4283 • CWE-400: Uncontrolled Resource Consumption •

https://notcve.org/view.php?id=CVE-2023-3354
11 Jul 2023 — A flaw was found in the QEMU built-in VNC server. When a client connects to the VNC server, QEMU checks whether the current number of connections crosses a certain threshold and if so, cleans up the previous connection. If the previous connection happens to be in the handshake phase and fails, QEMU cleans up the connection again, resulting in a NULL pointer dereference issue. This could allow a remote unauthenticated client to cause a denial of service. Gaoning Pan and Xingwei Li discovered that QEMU incorr... • https://access.redhat.com/security/cve/CVE-2023-3354 • CWE-476: NULL Pointer Dereference •

12 May 2023 — A flaw was found in OpenStack due to an inconsistency between Cinder and Nova. This issue can be triggered intentionally or by accident. A remote, authenticated attacker could exploit this vulnerability by detaching one of their volumes from Cinder. The highest impact is to confidentiality. Jan Wasilewski and Gorka Eguileor discovered that Glance_store incorrectly handled deleted volume attachments. • https://bugs.launchpad.net/bugs/2004555 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-440: Expected Behavior Violation •

10 Apr 2023 — 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.
