TITLE

libcurl Security hole

DESCRIPTION

A user can tell curl >= 7.20.0 and <= 7.78.0 to require a successful upgrade to TLS when speaking to an IMAP, POP3 or FTP server (`--ssl-reqd` on the command line or`CURLOPT_USE_SSL` set to `CURLUSESSL_CONTROL` or `CURLUSESSL_ALL` withlibcurl). This requirement could be bypassed if the server would return a properly crafted but perfectly legitimate response.This flaw would then make curl silently continue its operations **withoutTLS** contrary to the instructions and expectations, exposing possibly sensitive data in clear text over the network. A security issue was found in curl prior to 7.79.0. 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. Security Fix(es): * mig-controller: incorrect namespaces handling may lead to not authorized usage of Migration Toolkit for Containers (MTC) (CVE-2021-3948) 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. Solution: For details on how to install and use MTC, refer to: https://docs.openshift.com/container-platform/latest/migration_toolkit_for_containers/installing-mtc.html 4. 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. - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Gentoo Linux Security Advisory GLSA 202212-01 - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - https://security.gentoo.org/ - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Severity: High Title: curl: Multiple Vulnerabilities Date: December 19, 2022 Bugs: #803308, #813270, #841302, #843824, #854708, #867679, #878365 ID: 202212-01 - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Synopsis ======= Multiple vulnerabilities have been found in curl, the worst of which could result in arbitrary code execution.
