TITLE

GNU C Library Resource Management Error Vulnerability

DESCRIPTION

The mq_notify function in the GNU C Library (aka glibc) versions 2.32 and 2.33 has a use-after-free. It may use the notification thread attributes object (passed through its struct sigevent parameter) after it has been freed by the caller, leading to a denial of service (application crash) or possibly unspecified other impact. The vulnerability stems from the library's mq_notify function having a use-after-free feature. Bugs fixed (https://bugzilla.redhat.com/): 1944888 - CVE-2021-21409 netty: Request smuggling via content-length header 2004133 - CVE-2021-37136 netty-codec: Bzip2Decoder doesn't allow setting size restrictions for decompressed data 2004135 - CVE-2021-37137 netty-codec: SnappyFrameDecoder doesn't restrict chunk length and may buffer skippable chunks in an unnecessary way 2030932 - CVE-2021-44228 log4j-core: Remote code execution in Log4j 2.x when logs contain an attacker-controlled string value 5. JIRA issues fixed (https://issues.jboss.org/): LOG-1971 - Applying cluster state is causing elasticsearch to hit an issue and become unusable 6. Summary: The Migration Toolkit for Containers (MTC) 1.6.3 is now available. Description: The Migration Toolkit for Containers (MTC) enables you to migrate Kubernetes resources, persistent volume data, and internal container images between OpenShift Container Platform clusters, using the MTC web console or the Kubernetes API. Bugs fixed (https://bugzilla.redhat.com/): 2019088 - "MigrationController" CR displays syntax error when unquiescing applications 2021666 - Route name longer than 63 characters causes direct volume migration to fail 2021668 - "MigrationController" CR ignores the "cluster_subdomain" value for direct volume migration routes 2022017 - CVE-2021-3948 mig-controller: incorrect namespaces handling may lead to not authorized usage of Migration Toolkit for Containers (MTC) 2024966 - Manifests not used by Operator Lifecycle Manager must be removed from the MTC 1.6 Operator image 2027196 - "migration-controller" pod goes into "CrashLoopBackoff" state if an invalid registry route is entered on the "Clusters" page of the web console 2027382 - "Copy oc describe/oc logs" window does not close automatically after timeout 2028841 - "rsync-client" container fails during direct volume migration with "Address family not supported by protocol" error 2031793 - "migration-controller" pod goes into "CrashLoopBackOff" state if "MigPlan" CR contains an invalid "includedResources" resource 2039852 - "migration-controller" pod goes into "CrashLoopBackOff" state if "MigPlan" CR contains an invalid "destMigClusterRef" or "srcMigClusterRef" 5.
