TITLE

Systemd permission and access control issue vulnerability

DESCRIPTION

In systemd before v242-rc4, it was discovered that pam_systemd does not properly sanitize the environment before using the XDG_SEAT variable. It is possible for an attacker, in some particular configurations, to set a XDG_SEAT environment variable which allows for commands to be checked against polkit policies using the "allow_active" element rather than "allow_any". Systemd is a Linux-based system and service manager for Lennart Poettering software developers in Germany. The product is compatible with SysV and LSB startup scripts and provides a framework for representing dependencies between system services. A license and access control vulnerability exists in the systemdv242-rc4 release that stems from the lack of effective permissions and access control measures for network systems or products. An attacker could exploit this vulnerability to gain access to webmasters. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 ==================================================================== Red Hat Security Advisory Synopsis: Moderate: systemd security, bug fix, and enhancement update Advisory ID: RHSA-2021:1611-01 Product: Red Hat Enterprise Linux Advisory URL: https://access.redhat.com/errata/RHSA-2021:1611 Issue date: 2021-05-18 CVE Names: CVE-2019-3842 CVE-2020-13776 ==================================================================== 1. Summary: An update for systemd is now available for Red Hat Enterprise Linux 8. Red Hat Product Security has rated this update as having a security impact of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section. 2. Relevant releases/architectures: Red Hat Enterprise Linux BaseOS (v. 8) - aarch64, ppc64le, s390x, x86_64 3. It provides aggressive parallelism capabilities, uses socket and D-Bus activation for starting services, offers on-demand starting of daemons, and keeps track of processes using Linux cgroups. In addition, it supports snapshotting and restoring of the system state, maintains mount and automount points, and implements an elaborate transactional dependency-based service control logic. It can also work as a drop-in replacement for sysvinit. Security Fix(es): * systemd: Spoofing of XDG_SEAT allows for actions to be checked against "allow_active" instead of "allow_any" (CVE-2019-3842) * systemd: Mishandles numerical usernames beginning with decimal digits or 0x followed by hexadecimal digits (CVE-2020-13776) For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section. Additional Changes: For detailed information on changes in this release, see the Red Hat Enterprise Linux 8.4 Release Notes linked from the References section. 4. Solution: For details on how to apply this update, which includes the changes described in this advisory, refer to: https://access.redhat.com/articles/11258 5.

Description: Red Hat OpenShift Container Platform is Red Hat's cloud computing Kubernetes application platform solution designed for on-premise or private cloud deployments. This advisory contains the container images for Red Hat OpenShift Container Platform 4.7.13. See the following advisory for the RPM packages for this release: https://access.redhat.com/errata/RHSA-2021:2122 Space precludes documenting all of the container images in this advisory. See the following Release Notes documentation, which will be updated shortly for this release, for details about these changes: https://docs.openshift.com/container-platform/4.7/release_notes/ocp-4-7-rel ease-notes.html This update fixes the following bug among others: * Previously, resources for the ClusterOperator were being created early in the update process, which led to update failures when the ClusterOperator had no status condition while Operators were updating. This bug fix changes the timing of when these resources are created. As a result, updates can take place without errors.

Summary: Release of components for the Service Telemetry Framework 2. Description: Service Telemetry Framework (STF) provides automated collection of measurements and data from remote clients, such as Red Hat OpenStack Platform or third-party nodes. Bug fixes: * STF 1.3.3 now supports OpenShift Container Platform 4.8 as an installation platform. (BZ#2013268) * With this update, the servicetelemetrys.infra.watch CRD has a validation that limits the clouds[].name to 10 characters and alphanumeric to avoid issues with extra characters in the cloud name and names being too long. (BZ#2011603) * Previously, when you installed STF without having Elastic Cloud on Kubernetes (ECK) Operator installed, the following error message was returned: "Failed to find exact match for elasticsearch.k8s.elastic.co/v1beta1.Elasticsearch". The error was as a result of Service Telemetry Operator trying to look up information from a non-existent API interface. With this update, the Service Telemetry Operator verifies that the API exists before it attempts to make requests to the API interface that is provided by ECK. (BZ#1959166) 3. Dockerfiles and scripts should be amended either to refer to this new image specifically, or to the latest image generally. Bugs fixed (https://bugzilla.redhat.com/): 1959166 - Service Telemetry Operator can error out if ElasticSearch (ECK) CRD is not installed 1983596 - CVE-2021-34558 golang: crypto/tls: certificate of wrong type is causing TLS client to panic 2011603 - STF multi-cloud setup misinterprets name if a "-" is being used 2013268 - [RFE] Support STF 1.3 on OCP 4.8 5
