New! Vulnerability Priority Rating (VPR)
Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it's different from CVSS.

SynopsisThe remote Debian host is missing a security update.
DescriptionSeveral security vulnerabilities have been discovered in the Tomcat servlet and JSP engine.
An h2c direct connection to Apache Tomcat did not release the HTTP/1.1 processor after the upgrade to HTTP/2. If a sufficient number of such requests were made, an OutOfMemoryException could occur leading to a denial of service.
The payload length in a WebSocket frame was not correctly validated in Apache Tomcat. Invalid payload lengths could trigger an infinite loop.
Multiple requests with invalid payload lengths could lead to a denial of service.
For Debian 9 stretch, these problems have been fixed in version 8.5.54-0+deb9u3.
We recommend that you upgrade your tomcat8 packages.
For the detailed security status of tomcat8 please refer to its security tracker page at:
