CVE-2021-22876

TITLE

Red Hat Security Advisory 2021-5128-06

DESCRIPTION

curl 7.1.1 to and including 7.75.0 is vulnerable to an "Exposure of Private Personal Information to an Unauthorized Actor" by leaking credentials in the HTTP Referer: header. libcurl does not strip off user credentials from the URL when automatically populating the Referer: HTTP request header field in outgoing HTTP requests, and therefore risks leaking sensitive data to the server that is the target of the second HTTP request. This could lead to exposure of the credentials to the server to which requests were redirected. (CVE-2021-22876) A vulnerability was found in curl where a flaw in the option parser for sending NEW_ENV variables libcurl can pass uninitialized data from a stack-based buffer to the server. This issue leads to potentially revealing sensitive internal information to the server using a clear-text network protocol. The highest threat from this vulnerability is to confidentiality. (CVE-2021-22898). Summary: An update is now available for OpenShift Logging 5.1. 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. Solution: OSP 16.2.z Release - OSP Director Operator Containers 4. Bugs fixed (https://bugzilla.redhat.com/): 2025995 - Rebase tech preview on latest upstream v1.2.x branch 2030801 - CVE-2021-44716 golang: net/http: limit growth of header canonicalization cache 2036784 - osp controller (fencing enabled) in downed state after system manual crash test 5. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 ==================================================================== Red Hat Security Advisory Synopsis: Moderate: rh-dotnet31-curl security update Advisory ID: RHSA-2022:1354-01 Product: .NET Core on Red Hat Enterprise Linux Advisory URL: https://access.redhat.com/errata/RHSA-2022:1354 Issue date: 2022-04-13 CVE Names: CVE-2021-22876 CVE-2021-22924 CVE-2021-22946 CVE-2021-22947 ==================================================================== 1.
