Kategorie:	Denial of Service
Titel:	Apache Tomcat DoS Vulnerability - March19 (Linux)
Zusammenfassung:	Apache Tomcat is prone to a denial of service vulnerability in the HTTP/2; implementation.
Beschreibung:	Summary: Apache Tomcat is prone to a denial of service vulnerability in the HTTP/2 implementation. Vulnerability Insight: The HTTP/2 implementation accepts streams with excessive numbers of SETTINGS frames and also permitts clients to keep streams open without reading/writing request/response data. By keeping streams open for requests that utilises the Servlet API's blocking I/O, clients are able to cause server-side threads to block eventually leading to thread exhaustion and a DoS. Affected Software/OS: Apache Tomcat 8.5.0 to 8.5.37 and 9.0.0.M1 to 9.0.14. Solution: Update to version 8.5.38, 9.0.16 or later. CVSS Score: 5.0 CVSS Vector: AV:N/AC:L/Au:N/C:N/I:N/A:P
