CVE-2022-0670 3 Fedoraproject, Linuxfoundation, Redhat 3 Fedora, Ceph, Ceph Storage 2023-11-07 N/A 9.1 CRITICAL
A flaw was found in Openstack manilla owning a Ceph File system "share", which enables the owner to read/write any manilla share or entire file system. The vulnerability is due to a bug in the "volumes" plugin in Ceph Manager. This allows an attacker to compromise Confidentiality and Integrity of a file system. Fixed in RHCS 5.2 and Ceph 17.2.2.
CVE-2022-0324 1 Linuxfoundation 1 Software For Open Networking In The Cloud 2023-11-07 N/A 7.5 HIGH
There is a vulnerability in DHCPv6 packet parsing code that could be explored by remote attacker to craft a packet that could cause buffer overflow in a memcpy call, leading to out-of-bounds memory write that would cause dhcp6relay to crash. Dhcp6relay is a critical process and could cause dhcp relay docker to shutdown. Discovered by Eugene Lim of GovTech Singapore.
CVE-2021-43816 2 Fedoraproject, Linuxfoundation 2 Fedora, Containerd 2023-11-07 6.0 MEDIUM 9.1 CRITICAL
containerd is an open source container runtime. On installations using SELinux, such as EL8 (CentOS, RHEL), Fedora, or SUSE MicroOS, with containerd since v1.5.0-beta.0 as the backing container runtime interface (CRI), an unprivileged pod scheduled to the node may bind mount, via hostPath volume, any privileged, regular file on disk for complete read/write access (sans delete). Such is achieved by placing the in-container location of the hostPath volume mount at either `/etc/hosts`, `/etc/hostname`, or `/etc/resolv.conf`. These locations are being relabeled indiscriminately to match the container process-label which effectively elevates permissions for savvy containers that would not normally be able to access privileged host files. This issue has been resolved in version 1.5.9. Users are advised to upgrade as soon as possible.
CVE-2021-41190 2 Fedoraproject, Linuxfoundation 3 Fedora, Open Container Initiative Distribution Specification, Open Container Initiative Image Format Specification 2023-11-07 4.0 MEDIUM 5.0 MEDIUM
The OCI Distribution Spec project defines an API protocol to facilitate and standardize the distribution of content. In the OCI Distribution Specification version 1.0.0 and prior, the Content-Type header alone was used to determine the type of document during push and pull operations. Documents that contain both “manifests” and “layers” fields could be interpreted as either a manifest or an index in the absence of an accompanying Content-Type header. If a Content-Type header changed between two pulls of the same digest, a client may interpret the resulting content differently. The OCI Distribution Specification has been updated to require that a mediaType value present in a manifest or index match the Content-Type header used during the push and pull operations. Clients pulling from a registry may distrust the Content-Type header and reject an ambiguous document that contains both “manifests” and “layers” fields or “manifests” and “config” fields if they are unable to update to version 1.0.1 of the spec.
CVE-2021-30465 2 Fedoraproject, Linuxfoundation 2 Fedora, Runc 2023-11-07 6.0 MEDIUM 8.5 HIGH
runc before 1.0.0-rc95 allows a Container Filesystem Breakout via Directory Traversal. To exploit the vulnerability, an attacker must be able to create multiple containers with a fairly specific mount configuration. The problem occurs via a symlink-exchange attack that relies on a race condition.
CVE-2021-21334 2 Fedoraproject, Linuxfoundation 2 Fedora, Containerd 2023-11-07 4.3 MEDIUM 6.3 MEDIUM
In containerd (an industry-standard container runtime) before versions 1.3.10 and 1.4.4, containers launched through containerd's CRI implementation (through Kubernetes, crictl, or any other pod/container client that uses the containerd CRI service) that share the same image may receive incorrect environment variables, including values that are defined for other containers. If the affected containers have different security contexts, this may allow sensitive information to be unintentionally shared. If you are not using containerd's CRI implementation (through one of the mechanisms described above), you are not vulnerable to this issue. If you are not launching multiple containers or Kubernetes pods from the same image which have different environment variables, you are not vulnerable to this issue. If you are not launching multiple containers or Kubernetes pods from the same image in rapid succession, you have reduced likelihood of being vulnerable to this issue This vulnerability has been fixed in containerd 1.3.10 and containerd 1.4.4. Users should update to these versions.
CVE-2021-20206 1 Linuxfoundation 1 Container Network Interface 2023-11-07 6.5 MEDIUM 7.2 HIGH
An improper limitation of path name flaw was found in containernetworking/cni in versions before 0.8.1. When specifying the plugin to load in the 'type' field in the network configuration, it is possible to use special elements such as "../" separators to reference binaries elsewhere on the system. This flaw allows an attacker to execute other existing binaries other than the cni plugins/types, such as 'reboot'. The highest threat from this vulnerability is to confidentiality, integrity, as well as system availability.
CVE-2020-5258 3 Debian, Linuxfoundation, Oracle 10 Debian Linux, Dojo, Communications Application Session Controller and 7 more 2023-11-07 5.0 MEDIUM 7.7 HIGH
In affected versions of dojo (NPM package), the deepCopy method is vulnerable to Prototype Pollution. Prototype Pollution refers to the ability to inject properties into existing JavaScript language construct prototypes, such as objects. An attacker manipulates these attributes to overwrite, or pollute, a JavaScript application object prototype of the base object by injecting other values. This has been patched in versions 1.12.8, 1.13.7, 1.14.6, 1.15.3 and 1.16.2
CVE-2020-27847 1 Linuxfoundation 1 Dex 2023-11-07 7.5 HIGH 9.8 CRITICAL
A vulnerability exists in the SAML connector of the github.com/dexidp/dex library used to process SAML Signature Validation. This flaw allows an attacker to bypass SAML authentication. The highest threat from this vulnerability is to confidentiality, integrity, as well as system availability. This flaw affects dex versions before 2.27.0.
CVE-2020-26892 2 Fedoraproject, Linuxfoundation 2 Fedora, Nats-server 2023-11-07 7.5 HIGH 9.8 CRITICAL
The JWT library in NATS nats-server before 2.1.9 has Incorrect Access Control because of how expired credentials are handled.
CVE-2020-26521 2 Fedoraproject, Linuxfoundation 2 Fedora, Nats-server 2023-11-07 5.0 MEDIUM 7.5 HIGH
The JWT library in NATS nats-server before 2.1.9 allows a denial of service (a nil dereference in Go code).
CVE-2020-1760 5 Canonical, Debian, Fedoraproject and 2 more 6 Ubuntu Linux, Debian Linux, Fedora and 3 more 2023-11-07 4.3 MEDIUM 6.1 MEDIUM
A flaw was found in the Ceph Object Gateway, where it supports request sent by an anonymous user in Amazon S3. This flaw could lead to potential XSS attacks due to the lack of proper neutralization of untrusted input.
CVE-2020-1759 3 Fedoraproject, Linuxfoundation, Redhat 5 Fedora, Ceph, Ceph Storage and 2 more 2023-11-07 5.8 MEDIUM 6.8 MEDIUM
A vulnerability was found in Red Hat Ceph Storage 4 and Red Hat Openshift Container Storage 4.2 where, A nonce reuse vulnerability was discovered in the secure mode of the messenger v2 protocol, which can allow an attacker to forge auth tags and potentially manipulate the data by leveraging the reuse of a nonce in a session. Messages encrypted using a reused nonce value are susceptible to serious confidentiality and integrity attacks.
CVE-2020-1699 2 Linuxfoundation, Redhat 2 Ceph, Ceph Storage 2023-11-07 5.0 MEDIUM 7.5 HIGH
A path traversal flaw was found in the Ceph dashboard implemented in upstream versions v14.2.5, v14.2.6, v15.0.0 of Ceph storage and has been fixed in versions 14.2.7 and 15.1.0. An unauthenticated attacker could use this flaw to cause information disclosure on the host machine running the Ceph dashboard.
CVE-2020-15257 3 Debian, Fedoraproject, Linuxfoundation 3 Debian Linux, Fedora, Containerd 2023-11-07 3.6 LOW 5.2 MEDIUM
containerd is an industry-standard container runtime and is available as a daemon for Linux and Windows. In containerd before versions 1.3.9 and 1.4.3, the containerd-shim API is improperly exposed to host network containers. Access controls for the shim’s API socket verified that the connecting process had an effective UID of 0, but did not otherwise restrict access to the abstract Unix domain socket. This would allow malicious containers running in the same network namespace as the shim, with an effective UID of 0 but otherwise reduced privileges, to cause new processes to be run with elevated privileges. This vulnerability has been fixed in containerd 1.3.9 and 1.4.3. Users should update to these versions as soon as they are released. It should be noted that containers started with an old version of containerd-shim should be stopped and restarted, as running containers will continue to be vulnerable even after an upgrade. If you are not providing the ability for untrusted users to start containers in the same network namespace as the shim (typically the "host" network namespace, for example with docker run --net=host or hostNetwork: true in a Kubernetes pod) and run with an effective UID of 0, you are not vulnerable to this issue. If you are running containers with a vulnerable configuration, you can deny access to all abstract sockets with AppArmor by adding a line similar to deny unix addr=@**, to your policy. It is best practice to run containers with a reduced set of privileges, with a non-zero UID, and with isolated namespaces. The containerd maintainers strongly advise against sharing namespaces with the host. Reducing the set of isolation mechanisms used for a container necessarily increases that container's privilege, regardless of what container runtime is used for running that container.
CVE-2020-10753 5 Canonical, Fedoraproject, Linuxfoundation and 2 more 6 Ubuntu Linux, Fedora, Ceph and 3 more 2023-11-07 4.3 MEDIUM 6.5 MEDIUM
A flaw was found in the Red Hat Ceph Storage RadosGW (Ceph Object Gateway). The vulnerability is related to the injection of HTTP headers via a CORS ExposeHeader tag. The newline character in the ExposeHeader tag in the CORS configuration file generates a header injection in the response when the CORS request is made. Ceph versions 3.x and 4.x are vulnerable to this issue.
CVE-2020-10750 1 Linuxfoundation 1 Jaeger 2023-11-07 2.1 LOW 5.5 MEDIUM
Sensitive information written to a log file vulnerability was found in jaegertracing/jaeger before version 1.18.1 when the Kafka data store is used. This flaw allows an attacker with access to the container's log file to discover the Kafka credentials.
CVE-2020-10749 3 Fedoraproject, Linuxfoundation, Redhat 4 Fedora, Cni Network Plugins, Enterprise Linux and 1 more 2023-11-07 6.0 MEDIUM 6.0 MEDIUM
A vulnerability was found in all versions of containernetworking/plugins before version 0.8.6, that allows malicious containers in Kubernetes clusters to perform man-in-the-middle (MitM) attacks. A malicious container can exploit this flaw by sending rogue IPv6 router advertisements to the host or other containers, to redirect traffic to the malicious container.
CVE-2020-10736 1 Linuxfoundation 1 Ceph 2023-11-07 5.2 MEDIUM 8.0 HIGH
An authorization bypass vulnerability was found in Ceph versions 15.2.0 before 15.2.2, where the ceph-mon and ceph-mgr daemons do not properly restrict access, resulting in gaining access to unauthorized resources. This flaw allows an authenticated client to modify the configuration and possibly conduct further attacks.
CVE-2019-19921 5 Canonical, Debian, Linuxfoundation and 2 more 5 Ubuntu Linux, Debian Linux, Runc and 2 more 2023-11-07 4.4 MEDIUM 7.0 HIGH
runc through 1.0.0-rc9 has Incorrect Access Control leading to Escalation of Privileges, related to libcontainer/rootfs_linux.go. To exploit this, an attacker must be able to spawn two containers with custom volume-mount configurations, and be able to run custom images. (This vulnerability does not affect Docker due to an implementation detail that happens to block the attack.)
