Jenkins 2.274 and earlier, LTS 2.263.1 and earlier does not escape display names and IDs of item types shown on the New Item page, resulting in a stored cross-site scripting (XSS) vulnerability exploitable by attackers able to specify display names or IDs of item types.

The version of Jenkins Enterprise or Jenkins Operations Center running on the remote web server is 2.222.x prior to 2.222.43.0.1, 2.249.x prior to 2.249.30.0.1, or 2.x prior to 2.263.2.2. It is, therefore, affected by multiple vulnerabilities, including the following:

  - Jenkins 2.274 and earlier, LTS 2.263.1 and earlier allows attackers with permission to create or configure     various objects to inject crafted content into Old Data Monitor that results in the instantiation of     potentially unsafe objects once discarded by an administrator. (CVE-2021-21604)

  - Jenkins 2.274 and earlier, LTS 2.263.1 and earlier allows users with Agent/Configure permission to choose     agent names that cause Jenkins to override the global `config.xml` file. (CVE-2021-21605)

  - Jenkins 2.274 and earlier, LTS 2.263.1 and earlier does not correctly match requested URLs to the list of     always accessible paths, allowing attackers without Overall/Read permission to access some URLs as if they     did have Overall/Read permission. (CVE-2021-21609)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

    This advisory contains the RPM packages for Red Hat OpenShift Container     Platform 3.11.394. See the following advisory for the container images for this release:

    https://access.redhat.com/errata/RHBA-2021:0638

    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/3.11/release_notes/ocp_3_11_release_notes.html

    This update fixes the following bugs among others:

    * Previously, the restart-cluster playbook did not evaluate the defined cluster size for ops clusters.
    This was causing come clusters to never complete their restart. This bug fix passes the logging ops     cluster size, allowing restarts of ops clusters to complete successfully. (BZ#1879407)

    * Previously, the `openshift_named_certificates` role checked the contents of the `ca-bundle.crt` file     during cluster installation. This caused the check to fail during initial installation because the `ca-     bundle.crt` file is not yet created in that scenario. This bug fix allows the cluster to skip checking the     `ca-bundle.crt` file if it does not exist, resulting in initial installations succeeding. (BZ#1920567)

    * Previously, if the `openshift_release` attribute was not set in the Ansible inventory file, the nodes of     the cluster would fail during an upgrade. This was caused by the `cluster_facts.yml` file being gathered     before the `openshift_release` attribute was defined by the upgrade playbook. Now the `cluster_facts.yml`     file is gathered after the `openshift_version` role runs and the `openshift_release` attribute is set,     allowing for successful node upgrades. (BZ#1921353)

    All OpenShift Container Platform 3.11 users are advised to upgrade to these updated packages and images.
