EulerOS 2.0 SP8 : tomcat (EulerOS-SA-2019-1772)

medium Nessus Plugin ID 127009

Synopsis

The remote EulerOS host is missing multiple security updates.

Description

According to the versions of the tomcat packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

- When the default servlet in Apache Tomcat versions 9.0.0.M1 to 9.0.11, 8.5.0 to 8.5.33 and 7.0.23 to 7.0.90 returned a redirect to a directory (e.g.
redirecting to '/foo/' when the user requested '/foo') a specially crafted URL could be used to cause the redirect to be generated to any URI of the attackers choice.(CVE-2018-11784)

- 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.(CVE-2019-0199)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Update the affected tomcat packages.
