TITLE

HAXX libcurl Information disclosure vulnerability

DESCRIPTION

A malicious server can use the FTP PASV response to trick curl 7.73.0 and earlier into connecting back to a given IP address and port, and this way potentially make curl extract information about services that are otherwise private and not disclosed, for example doing port scanning and service banner extractions. HAXX Haxx curl is a set of file transfer tools that use the URL syntax to work under the command line of the Swedish Haxx (HAXX) company. The tool supports file upload and download and includes a libcurl (client URL transfer library) for program development. Attackers can use this vulnerability to bypass data access restrictions and obtain sensitive information through curl's FTP PASV Responses.

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.

This could result in data being sent to the wrong destination, possibly exposing sensitive information. This issue only affected Ubuntu 20.10. (CVE-2020-8231) Varnavas Papaioannou discovered that curl incorrectly handled FTP PASV responses. (CVE-2020-8284) It was discovered that curl incorrectly handled FTP wildcard matchins.
