Openshift Container Platform

A flaw was found in the way HAProxy processed HTTP responses containing the "Set-Cookie2" header. This flaw could allow an attacker to send crafted HTTP response packets which lead to an infinite loop, eventually resulting in a denial of service condition. The highest threat from this vulnerability is availability.Show less

It was found that polkit could be tricked into bypassing the credential checks for D-Bus requests, elevating the privileges of the requestor to the root user. This flaw could be used by an unprivileged local attacker to, for example, create a new local administrator. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.Show less

An incorrect sysctls validation vulnerability was found in CRI-O 1.18 and earlier. The sysctls from the list of "safe" sysctls specified for the cluster will be applied to the host if an attacker is able to create a pod with a hostIPC and hostNetwork kernel namespace.Show less

JMSAppender in Log4j 1.2 is vulnerable to deserialization of untrusted data when the attacker has write access to the Log4j configuration. The attacker can provide TopicBindingName and TopicConnectionFactoryBindingName configurations causing JMSAppender to perform JNDI requests that result in remote code execution in a similar fashion to CVE-2021-44228. Note this issue only affects Log4j 1.2 when specifically configured to use JMSAppender, which is not the default. Apache Log4j 1.2 reached end of life in August 2015. Users should upgrade to Log4j 2 as it addresses numerous other issues from the previous versions.Show less

A flaw was found in noobaa-core in versions before 5.7.0. This flaw results in the name of an arbitrarily URL being copied into an HTML document as plain text between tags, including potentially a payload script. The input was echoed unmodified in the application response, resulting in arbitrary JavaScript being injected into an application's response. The highest threat to the system is for confidentiality, availability, and integrity.Show less

A flaw was found in the Restricted Security Context Constraints (SCC), where it allows pods to craft custom network packets. This flaw allows an attacker to cause a denial of service attack on an OpenShift Container Platform cluster if they can deploy pods. The highest threat from this vulnerability is to system availability.Show less

It was discovered that OpenShift Container Platform's (OCP) distribution of Kibana could open in an iframe, which made it possible to intercept and manipulate requests. This flaw allows an attacker to trick a user into performing arbitrary actions in OCP's distribution of Kibana, such as clickjacking.Show less

A Zip Slip vulnerability was found in the oc binary in openshift-clients where an arbitrary file write is achieved by using a specially crafted raw container image (.tar file) which contains symbolic links. The vulnerability is limited to the command `oc image extract`. If a symbolic link is first created pointing within the tarball, this allows further symbolic links to bypass the existing path check. This flaw allows the tarball to create links outside the tarball's parent directory, allowing for executables or configuration files to be overwritten, resulting in arbitrary code execution. The highest threat from this vulnerability is to confidentiality, integrity, as well as system availability. Versions up to and including openshift-clients-4.7.0-202104250659.p0.git.95881af are affected.Show less

A deadlock vulnerability was found in 'github.com/containers/storage' in versions before 1.28.1. When a container image is processed, each layer is unpacked using `tar`. If one of those layers is not a valid `tar` archive this causes an error leading to an unexpected situation where the code indefinitely waits for the tar unpacked stream, which never finishes. An attacker could use this vulnerability to craft a malicious image, which when downloaded and stored by an application using containers/storage, would then cause a deadlock leading to a Denial of Service (DoS).Show less

An insecure modification vulnerability in the /etc/passwd file was found in the operator-framework/hadoop as shipped in Red Hat Openshift 4. An attacker with access to the container could use this flaw to modify /etc/passwd and escalate their privileges.Show less

An insecure modification vulnerability in the /etc/passwd file was found in the operator-framework/hive as shipped in Red Hat Openshift 4. An attacker with access to the container could use this flaw to modify /etc/passwd and escalate their privileges.Show less

An insecure modification vulnerability in the /etc/passwd file was found in the operator-framework/presto as shipped in Red Hat Openshift 4. An attacker with access to the container could use this flaw to modify /etc/passwd and escalate their privileges.Show less

An infinite loop in SMLLexer in Pygments versions 1.5 to 2.7.3 may lead to denial of service when performing syntax highlighting of a Standard ML (SML) source file, as demonstrated by input that only contains the "exception" keyword.Show less

A flaw was found in atomic-openshift of openshift-4.2 where the basic-user RABC role in OpenShift Container Platform doesn't sufficiently protect the GlusterFS StorageClass against leaking of the restuserkey. An attacker with basic-user permissions is able to obtain the value of restuserkey, and use it to authenticate to the GlusterFS REST service, gaining access to read, and modify files.Show less

A flaw was discovered in OpenShift Container Platform 4 where, by default, users with access to create pods also have the ability to schedule workloads on master nodes. Pods with permission to access the host network, running on master nodes, can retrieve security credentials for the master AWS IAM role, allowing management access to AWS resources. With access to the security credentials, the user then has access to the entire infrastructure. Impact to data and system availability is high.Show less

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. The highest threat from this vulnerability is to system availability.Show less

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.Show less

A flaw was found in the fabric8 kubernetes-client in version 4.2.0 and after. This flaw allows a malicious pod/container to cause applications using the fabric8 kubernetes-client `copy` command to extract files outside the working path. The highest threat from this vulnerability is to integrity and system availability. This has been fixed in kubernetes-client-4.13.2 kubernetes-client-5.0.2 kubernetes-client-4.11.2 kubernetes-client-4.7.2Show less

A NULL pointer dereference flaw was found in the Linux kernel's GPU Nouveau driver functionality in versions prior to 5.12-rc1 in the way the user calls ioctl DRM_IOCTL_NOUVEAU_CHANNEL_ALLOC. This flaw allows a local user to crash the system.Show less
