Summary
Red Hat Security Advisory: Red Hat JBoss Web Server 5.6.0 Security release

Notes

Topic
Red Hat JBoss Web Server 5.6.0 zip release is now available for Red Hat Enterprise Linux 7, Red Hat Enterprise Linux 8, and Microsoft Windows. Red Hat Product Security has rated this release as having a security impact of Important. 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 JBoss Web Server is a fully integrated and certified set of components for hosting Java web applications. It is comprised of the Apache Tomcat Servlet container, JBoss HTTP Connector (mod_cluster), the PicketLink Vault extension for Apache Tomcat, and the Tomcat Native library. This release of Red Hat JBoss Web Server 5.6.0 serves as a replacement for Red Hat JBoss Web Server 5.5.0. This release includes bug fixes, enhancements and component upgrades, which are documented in the Release Notes, linked to in the References. Security Fix(es): * tomcat: OutOfMemoryError caused by HTTP upgrade connection leak could lead to DoS (CVE-2021-42340) * tomcat: HTTP request smuggling when used with a reverse proxy (CVE-2021-33037) * tomcat: JNDI realm authentication weakness (CVE-2021-30640) 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.
