CVSS: 7.0EPSS: 0%CPEs: 4EXPL: 0CVE-2021-20188 – podman: container users permissions are not respected in privileged containers
https://notcve.org/view.php?id=CVE-2021-20188
A flaw was found in podman before 1.7.0. File permissions for non-root users running in a privileged container are not correctly checked. This flaw can be abused by a low-privileged user inside the container to access any other file in the container, even if owned by the root user inside the container. It does not allow to directly escape the container, though being a privileged container means that a lot of security features are disabled when running the container. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability. • https://bugzilla.redhat.com/show_bug.cgi?id=1915734 https://access.redhat.com/security/cve/CVE-2021-20188 • CWE-863: Incorrect Authorization •

https://notcve.org/view.php?id=CVE-2021-3344
A privilege escalation flaw was found in OpenShift builder. During build time, credentials outside the build context are automatically mounted into the container image under construction. An OpenShift user, able to execute code during build time inside this container can re-use the credentials to overwrite arbitrary container images in internal registries and/or escalate their privileges. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability. This affects github.com/openshift/builder v0.0.0-20210125201112-7901cb396121 and before. • https://bugzilla.redhat.com/show_bug.cgi?id=1921450 https://access.redhat.com/security/cve/CVE-2021-3344 • CWE-522: Insufficiently Protected Credentials •

https://notcve.org/view.php?id=CVE-2021-20182
A privilege escalation flaw was found in openshift4/ose-docker-builder. The build container runs with high privileges using a chrooted environment instead of runc. If an attacker can gain access to this build container, they can potentially utilize the raw devices of the underlying node, such as the network and storage devices, to at least escalate their privileges to that of the cluster admin. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.

A flaw was found in multiple versions of OpenvSwitch. Specially crafted LLDP packets can cause memory to be lost when allocating data to handle specific optional TLVs, potentially causing a denial of service.

A flaw was found in cluster-ingress-operator.
