TITLE

Apache Tomcat Vulnerable to resource exhaustion

DESCRIPTION

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. Apache Tomcat Contains a resource exhaustion vulnerability.Service operation interruption (DoS) There is a possibility of being put into a state. Apache Tomcat is a lightweight web application server from the Apache Software Foundation. This program implements support for Servlet and JavaServerPage (JSP). There is a security vulnerability in Apache Tomcat. An attacker could exploit the vulnerability to cause a denial of service. Attackers may leverage this issue to cause denial-of-service conditions. A vulnerability in Apache Tomcat could allow an unauthenticated, remote malicious user to cause a denial of service (DoS) condition on a targeted system. The vulnerability is due to a resource exhaustion condition in the HTTP/2 implementation of the affected software. A successful exploit could result in a DoS condition on the targeted system. Apache has confirmed the vulnerability and released software updates. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 - ------------------------------------------------------------------------- Debian Security Advisory DSA-4596-1 security@debian.org https://www.debian.org/security/ Moritz Muehlenhoff December 27, 2019 https://www.debian.org/security/faq - ------------------------------------------------------------------------- Package : tomcat8 CVE ID : CVE-2018-8014 CVE-2018-11784 CVE-2019-0199 CVE-2019-0221 CVE-2019-12418 CVE-2019-17563 Several issues were discovered in the Tomcat servlet and JSP engine, which could result in session fixation attacks, information disclosure, cross- site scripting, denial of service via resource exhaustion and insecure redirects. For the oldstable distribution (stretch), these problems have been fixed in version 8.5.50-0+deb9u1. This update also requires an updated version of tomcat-native which has been updated to 1.2.21-1~deb9u1. We recommend that you upgrade your tomcat8 packages.
