CVE-2020-10878

TITLE

Red Hat Security Advisory 2021-1032-01

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. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 ===================================================================== Red Hat Security Advisory Synopsis: Moderate: perl security update Advisory ID: RHSA-2021:1032-01 Product: Red Hat Enterprise Linux Advisory URL: https://access.redhat.com/errata/RHSA-2021:1032 Issue date: 2021-03-30 CVE Names: CVE-2020-10543 CVE-2020-10878 CVE-2020-12723 ===================================================================== 1.

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.
