CVE-2019-0199 (GCVE-0-2019-0199)

Vulnerability from cvelistv5 – Published: 2019-04-10 14:21 – Updated: 2024-08-04 17:44
VLAI
Summary
The HTTP/2 implementation in Apache Tomcat 9.0.0.M1 to 9.0.14 and 8.5.0 to 8.5.37 accepted streams with excessive numbers of SETTINGS frames and also permitted clients to keep streams open without reading/writing request/response data. By keeping streams open for requests that utilised the Servlet API's blocking I/O, clients were able to cause server-side threads to block eventually leading to thread exhaustion and a DoS.
Severity
