UBUNTU-CVE-2024-23672
A denial of service vulnerability exists in Apache Tomcat due to incomplete cleanup of WebSocket connections. WebSocket clients could keep connections open, causing increased resource consumption. This affects multiple Apache Tomcat versions from 8.5.0 through 8.5.98, 9.0.0-M1 through 9.0.85, 10.1.0-M1 through 10.1.18, and 11.0.0-M1 through 11.0.0-M16. Users are advised to upgrade to fixed versions 8.5.99, 9.0.86, 10.1.19, or 11.0.0-M17 to address the issue.
AI Analysis
Technical Summary
Apache Tomcat contains a denial of service vulnerability caused by incomplete cleanup of WebSocket connections. WebSocket clients could maintain open connections, leading to increased resource consumption and potential service disruption. The vulnerability affects Apache Tomcat versions from 11.0.0-M1 through 11.0.0-M16, 10.1.0-M1 through 10.1.18, 9.0.0-M1 through 9.0.85, and 8.5.0 through 8.5.98. The issue is resolved in versions 11.0.0-M17, 10.1.19, 9.0.86, and 8.5.99. Multiple Ubuntu package versions are affected as listed, including versions from 7.0.42-1 through 10.1.16-1.
Potential Impact
Successful exploitation can cause denial of service by exhausting server resources through persistent WebSocket connections, potentially disrupting normal service availability. There is no indication of confidentiality or integrity impact beyond resource exhaustion.
Mitigation Recommendations
A fix is available. Users should upgrade Apache Tomcat to versions 11.0.0-M17, 10.1.19, 9.0.86, or 8.5.99 or later to remediate this vulnerability. The vendor advisory confirms these versions contain the fix. No additional mitigation steps are indicated.
