TITLE

Haxx libcurl Information disclosure vulnerability

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). 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-1775 - [release-5.2] Syslog output is serializing json incorrectly LOG-1824 - [release-5.2] Rejected by Elasticsearch and unexpected json-parsing LOG-1963 - [release-5.2] CLO panic: runtime error: slice bounds out of range [:-1] LOG-1970 - 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. 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.
