Red Hat Security Advisory: Red Hat JBoss Web Server 5.8.4 release and security update
Red Hat JBoss Web Server 5.8.4 includes security fixes addressing two vulnerabilities in Apache Tomcat components. The first is an incomplete fix for a time-of-check to time-of-use (TOCTOU) issue in JSP compilation that can lead to remote code execution (CVE-2024-56337). The second is a denial-of-service (DoS) vulnerability triggered by malformed HTTP/2 PRIORITY_UPDATE frames (CVE-2025-31650). This release replaces version 5.8.3 and includes other bug fixes and enhancements.

Technical Summary
Red Hat JBoss Web Server 5.8.4 addresses two security vulnerabilities in its Apache Tomcat components. CVE-2024-56337 is a remote code execution vulnerability caused by a TOCTOU issue during JSP compilation, representing an incomplete fix of a prior CVE-2024-50379.

The advisory does not specify exact affected versions but indicates that updating to 5.8.4 is the remediation.
Potential Impact
Successful exploitation of CVE-2024-56337 could allow remote code execution on affected systems, posing a high security risk. CVE-2025-31650 could allow an attacker to cause denial of service by sending malformed HTTP/2 PRIORITY_UPDATE frames, impacting availability. Both vulnerabilities affect the Apache Tomcat components within Red Hat JBoss Web Server 5.8.x. No known exploits in the wild have been reported at this time.
