EulerOS 2.0 SP8 : tomcat (EulerOS-SA-2020-2324)

medium Nessus Plugin ID 142170

Synopsis

The remote EulerOS host is missing a security update.

Description

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

 - If an HTTP/2 client connecting to Apache Tomcat 10.0.0-M1 to 10.0.0-M7, 9.0.0.M1 to 9.0.37 or 8.5.0 to 8.5.57 exceeded the agreed maximum number of concurrent streams for a connection (in violation of the HTTP/2 protocol), it was possible that a subsequent request made on that connection could contain HTTP headers - including HTTP/2 pseudo headers - from a previous request rather than the intended headers. This could lead to users seeing responses for unexpected resources.(CVE-2020-13943)

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 package.
