When libvirtd is configured by OSP director (tripleo-heat-templates) to use the TLS transport it defaults to the same certificate authority as all non-libvirtd services. As no additional authentication is configured this allows these services to connect to libvirtd (which is equivalent to root access). If a vulnerability exists in another service it could, combined with this flaw, be exploited to escalate privileges to gain control over compute nodes.
A flaw was found in openstack-keystone, only the first 72 characters of an application secret are verified allowing attackers bypass some password complexity which administrators may be counting on. The highest threat from this vulnerability is to data confidentiality and integrity. A patch is available.
An an information leak was discovered in OpenStack's undercloud. Rsync stores sensitive swift data (for example administrative credentials to the overcloud) in a manner that makes this information visible to local users of the undercloud. This enables potentially anyone with network access to the undercloud to further gain access to the rest of an OpenStack deployment.
A permissive list of allowed inputs flaw was found in DPDK. This issue allows a remote attacker to cause a denial of service triggered by sending a crafted Vhost header to DPDK.
QEMU before 2.0.0 block drivers for CLOOP, QCOW2 version 2 and various other image formats are vulnerable to potential memory corruptions, integer/buffer overflows or crash caused by missing input validations which could allow a remote user to execute arbitrary code on the host with the privileges of the QEMU process.
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 (nwproto 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.
An authorization flaw was found in openstack-barbican. The default policy rules for the secret metadata API allowed any authenticated user to add, modify, or delete metadata from any secret regardless of ownership. This flaw allows an attacker on the network to modify or delete protected data, causing a denial of service by consuming protected resources.
A flaw was found in OpenStack. Multiple components show plain-text passwords in /var/log/messages during the OpenStack overcloud update run, leading to a disclosure of sensitive information problem.
A flaw was found in python-rsa, where it is vulnerable to Bleichenbacher timing attacks. This flaw allows an attacker, via the RSA decryption API, to decrypt parts of the ciphertext encrypted with RSA. The highest threat from this vulnerability is to confidentiality.
A regression was introduced in the Red Hat build of python-eventlet due to a change in the patch application strategy, resulting in a patch for CVE-2021-21419 not being applied for all builds of all products.
An incomplete fix for CVE-2023-1625 in openstack-heat was discovered. Some sensitive information may still be disclosed through openstack stack abandon command even with the hidden feature set to True and CVE-2023-1625 fix applied.

An information leak was discovered in openstack heat. https://review.opendev.org/c/openstack/heat/+/868166 https://github.com/openstack/heat/commit/a49526c278e52823080c7f3fcb72785b93fd4dcb
The get stack environment API doesn't mask hidden parameter values. A malicious system user can get sensitive data by this API even though encryptparametersandproperties option is set to true. All VMs deployed by this heat template may be compromised.
A flaw was found in openstack-neutron's default Open vSwitch firewall rules. By sending carefully crafted packets, anyone in control of a server instance connected to the virtual switch can impersonate the IPv6 addresses of other systems on the network, resulting in denial of service or in some cases possibly interception of traffic intended for other destinations. Only deployments using the Open vSwitch driver are affected. Source: OpenStack project. Versions before openstack-neutron 15.3.3, openstack-neutron 16.3.1 and openstack-neutron 17.1.1 are affected.
A flaw was found in the Ansible Engine, in ansible-engine 2.8.x before 2.8.15 and ansible-engine 2.9.x before 2.9.13, when installing packages using the dnf module. GPG signatures are ignored during installation even when disablegpgcheck is set to False, which is the default behavior. This flaw leads to malicious packages being installed on the system and arbitrary code executed via package installation scripts. The highest threat from this vulnerability is to integrity and system availability.
A barbican configuration file is set to world-readable in Red Hat OpenStack. This presents a security risk as it allows authenticated attacker with limited access to the file to view its contents, including secure credential.
A key length flaw was found in Red Hat Ceph Storage. An attacker can exploit the fact that the key length is incorrectly passed in an encryption algorithm to create a non random key, which is weaker and can be exploited for loss of confidentiality and integrity on encrypted disks.
An improper authorization flaw was discovered in openstack-selinux's applied policy where it does not prevent a non-root user in a container from privilege escalation. A non-root attacker in one or more Red Hat OpenStack (RHOSP) containers could send messages to the dbus. With access to the dbus, the attacker could start or stop services, possibly causing a denial of service. Versions before openstack-selinux 0.8.24 are affected.
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.
An infinite loop flaw was found in the e1000 NIC emulator of the QEMU. This issue occurs while processing transmits (tx) descriptors in processtxdesc if various descriptor fields are initialized with invalid values. This flaw allows a guest to consume CPU cycles on the host, resulting in a denial of service. The highest threat from this vulnerability is to system availability.

Qemu before 1.6.2 block diver for the various disk image formats used by Bochs and for the QCOW version 2 format, are vulnerable to a possible crash caused by signed data types or a logic error while creating QCOW2 snapshots, which leads to incorrectly calling updaterefcount() routine.
A vulnerability was found in openstack-nova's console proxy, noVNC. By crafting a malicious URL, noVNC could be made to redirect to any desired URL.
A container isolation flaw was discovered in Red Hat OpenStack, allowing an attacker with limited authentication and access to Barbican containers to potentially access other OpenStack containers and services. This is possible as they share common CGROUP and namespace.
A flaw was found in the openstack-barbican component. This issue allows an access policy bypass via a query string when accessing the API.
Qemu before 2.0 block driver for Hyper-V VHDX Images is vulnerable to infinite loops and other potential issues when calculating BAT entries, due to missing bounds checks for blocksize and logicalsectorsize variables. These are used to derive other fields like 'sectorsperblock' etc. A user able to alter the Qemu disk image could ise this flaw to crash the Qemu instance resulting in DoS.
A flaw was found in Wildfly, where it returns an incorrect caller principal under certain heavily concurrent situations when Elytron Security is used. This flaw allows an attacker to gain improper access to information they should not have.
An authorization flaw was found in openstack-barbican, where anyone with an admin role could add secrets to a different project container. This flaw allows an attacker on the network to consume protected resources and cause a denial of service.
A null pointer dereference issue was found in the IDE disk emulator of QEMU. It could occur while cancelling an i/o operation via idecanceldmasync() routine, if a block drive pointer is null. A guest may use this flaw to crash the QEMU process on the host resulting in DoS scenario.
