TITLE

Perl Input validation error vulnerability

DESCRIPTION

Perl before 5.30.3 has an integer overflow related to mishandling of a "PL_regkind[OP(n)] == NOTHING" situation. A crafted regular expression could lead to malformed bytecode with a possibility of instruction injection. An input validation error vulnerability exists in Perl versions prior to 5.30.3. The vulnerability is caused by the program's incorrect handling of the \"PL_regkind[OP(n)] == NOTHING\" case. Bug fix: * RHACM 2.0.8 images (BZ #1915461) 3. Bugs fixed (https://bugzilla.redhat.com/): 1915461 - RHACM 2.0.8 images 1921650 - CVE-2021-3121 gogo/protobuf: plugin/unmarshal/unmarshal.go lacks certain index validation 5. Description: Red Hat Advanced Cluster Management for Kubernetes 2.2.4 images Red Hat Advanced Cluster Management for Kubernetes provides the capabilities to address common challenges that administrators and site reliability engineers face as they work across a range of public and private cloud environments. Clusters and applications are all visible and managed from a single console—with security policy built in.

Summary: Red Hat OpenShift Container Platform release 4.7.13 is now available with updates to packages and images that fix several bugs. This release includes a security update for Red Hat OpenShift Container Platform 4.7. 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. Description: Red Hat OpenShift Container Platform is Red Hat's cloud computing Kubernetes application platform solution designed for on-premise or private cloud deployments. 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. 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. (BZ#1959238) Security Fix(es): * gogo/protobuf: plugin/unmarshal/unmarshal.go lacks certain index validation (CVE-2021-3121) You may download the oc tool and use it to inspect release image metadata as follows: (For x86_64 architecture) $ oc adm release info quay.io/openshift-release-dev/ocp-release:4.7.13-x86_64 The image digest is sha256:783a2c963f35ccab38e82e6a8c7fa954c3a4551e07d2f43c06098828dd986ed4 (For s390x architecture) $ oc adm release info quay.io/openshift-release-dev/ocp-release:4.7.13-s390x The image digest is sha256:4cf44e68413acad063203e1ee8982fd01d8b9c1f8643a5b31cd7ff341b3199cd (For ppc64le architecture) $ oc adm release info quay.io/openshift-release-dev/ocp-release:4.7.13-ppc64le The image digest is sha256:d47ce972f87f14f1f3c5d50428d2255d1256dae3f45c938ace88547478643e36 All OpenShift Container Platform 4.7 users are advised to upgrade to these updated packages and images when they are available in the appropriate release channel.
