EulerOS 2.0 SP8 : tomcat (EulerOS-SA-2019-2094)
Medium Nessus Plugin ID 129453
SynopsisThe remote EulerOS host is missing a security update.
DescriptionAccording to the version of the tomcat packages installed, the EulerOS installation on the remote host is affected by the following vulnerability :
- The fix for CVE-2019-0199 was incomplete and did not address HTTP/2 connection window exhaustion on write in Apache Tomcat versions 9.0.0.M1 to 9.0.19 and 8.5.0 to 8.5.40 . By not sending WINDOW_UPDATE messages for the connection window (stream 0) clients were able to cause server-side threads to block eventually leading to thread exhaustion and a DoS.(CVE-2019-10072)
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.
SolutionUpdate the affected tomcat package.
