CVE-2020-27781 – ceph: User credentials can be manipulated and stolen by Native CephFS consumers of OpenStack Manila
https://notcve.org/view.php?id=CVE-2020-27781
User credentials can be manipulated and stolen by Native CephFS consumers of OpenStack Manila, resulting in potential privilege escalation. An Open Stack Manila user can request access to a share to an arbitrary cephx user, including existing users. The access key is retrieved via the interface drivers. Then, all users of the requesting OpenStack project can view the access key. This enables the attacker to target any resource that the user has access to. • https://bugzilla.redhat.com/show_bug.cgi?id=1900109 https://lists.debian.org/debian-lts-announce/2023/10/msg00034.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/ZJ7FFROL25FYRL6FMI33VRKOD74LINRP https://security.gentoo.org/glsa/202105-39 https://access.redhat.com/security/cve/CVE-2020-27781 • CWE-522: Insufficiently Protected Credentials •

CVE-2020-1690 – openstack-selinux: policy flaw allows dbus messaging
https://notcve.org/view.php?id=CVE-2020-1690
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. Se ha detectado un fallo de autorización inapropiada en la política aplicada de openstack-selinux, que no impide a un usuario no root en un contenedor pueda escalar sus privilegios. • https://bugzilla.redhat.com/show_bug.cgi?id=1789640 https://access.redhat.com/security/cve/CVE-2020-1690 • CWE-285: Improper Authorization •

CVE-2020-14365 – ansible: dnf module install packages with no GPG signature
https://notcve.org/view.php?id=CVE-2020-14365
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 disable_gpg_check 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. Se encontró un fallo en Ansible Engine, en ansible-engine versiones 2.8.x anteriores a 2.8.15 y ansible-engine versiones 2.9.x anteriores a 2.9.13, Cuando se instalan paquetes usando el módulo dnf. • https://bugzilla.redhat.com/show_bug.cgi?id=1869154 https://www.debian.org/security/2021/dsa-4950 https://access.redhat.com/security/cve/CVE-2020-14365 • CWE-347: Improper Verification of Cryptographic Signature •
