AI Analysis
Technical Summary
Red Hat JBoss Web Server 5.8.4 addresses two security issues in the Apache Tomcat components it includes. The first is CVE-2024-56337, an incomplete fix for a previously reported RCE vulnerability (CVE-2024-50379) caused by a TOCTOU issue in JSP compilation, allowing potential remote code execution. The second is CVE-2025-31650, a denial-of-service vulnerability triggered by malformed HTTP/2 PRIORITY_UPDATE frames. These vulnerabilities affect the Tomcat servlet container within the JBoss Web Server stack. The update replaces version 5.8.3 and is available for Red Hat Enterprise Linux 7, 8, 9, and Windows Server platforms. No CVSS scores are provided in the advisory, but the issues are rated as important by Red Hat.
Potential Impact
The vulnerabilities could allow an attacker to remotely execute code due to a TOCTOU issue in JSP compilation (CVE-2024-56337) and cause denial-of-service conditions via malformed HTTP/2 PRIORITY_UPDATE frames (CVE-2025-31650). These impact the availability and potentially the integrity of applications hosted on affected Red Hat JBoss Web Server versions. No known exploits in the wild have been reported at this time.
Mitigation Recommendations
Red Hat has released JBoss Web Server 5.8.4 to address these vulnerabilities. Users should apply this update promptly after backing up their existing installations and configurations. The update replaces version 5.8.3 and includes fixes for both CVE-2024-56337 and CVE-2025-31650. No alternative mitigations or workarounds are specified in the advisory.
