Summary
Red Hat Security Advisory: Red Hat AMQ Streams 2.0.0 release and security update

Notes

Topic
Red Hat AMQ Streams 2.0.0 is now available from the Red Hat Customer Portal. 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.
Details
Red Hat AMQ Streams, based on the Apache Kafka project, offers a distributed backbone that allows microservices and other applications to share data with extremely high throughput and extremely low latency. This release of Red Hat AMQ Streams 2.0.0 serves as a replacement for Red Hat AMQ Streams 1.8.4, and includes security and bug fixes, and enhancements. Security Fix(es): * jetty: crafted URIs allow bypassing security constraints (CVE-2021-34429) * netty-codec: Bzip2Decoder doesn't allow setting size restrictions for decompressed data (CVE-2021-37136) * netty-codec: SnappyFrameDecoder doesn't restrict chunk length and may buffer skippable chunks in an unnecessary way (CVE-2021-37137) * Kafka: Timing Attack Vulnerability for Apache Kafka Connect and Clients (CVE-2021-38153) * log4j-core: remote code execution via JDBC Appender (CVE-2021-44832) 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 is not the default configuration for end-applications using log4j 2.x and would require explicit action from a privileged user (a developer or administrator) to access the vulnerability. \nIn certain non-default configurations, it was found that the fix to address CVE-2021-44228 in Apache Log4j 2.15.0 was insufficient.\n\nThis issue affects the log4j version between 2.0 and 2.15. Log4j 1.x is NOT impacted by this vulnerability. \n\nPrerequisites to exploit this flaw are :\n\n- A remotely accessible endpoint with any protocol (HTTP, TCP, etc) that allows an attacker to send arbitrary data,\n- A log statement in the endpoint that logs the attacker controlled data.\n- Log4j configuration file should be explicitly configured to use a non-default Pattern Layout with a Context Lookup eg. ($${ctx:loginId}) \n\nIn most cases, the mitigation suggested for CVE-2021-44228 (i.e. to set the system property `log4j2.noFormatMsgLookup` to `true) does NOT mitigate this specific vulnerability. \nLog4j 2.16.0 fixes this issue by removing support for message lookup patterns and disabling JNDI functionality by default.\n\nFor Elasticsearch, as shipped in OpenShift 3.11, the \"log4j2.formatMsgNoLookups=true\" system property mitigation is sufficient as there are no included non-standard configurations that allow for exploitation:\n\nhttps://github.com/openshift/openshift-ansible/blob/release-3.11/roles/openshift_logging_elasticsearch/templates/log4j2.properties.j2\n\nhttps://discuss.elastic.co/t/apache-log4j2-remote-code-execution-rce-vulnerability-cve-2021-44228-esa-2021-31/291476\n\nFor CodeReady Studio the fix for this flaw is available on CodeReady Studio 12.21.3 and above versions.",
