Debian DLA-2495-1 : tomcat8 security update

high Nessus Plugin ID 144343

Language:

Synopsis

The remote Debian host is missing a security update.

Description

It was discovered that Apache Tomcat from 8.5.0 to 8.5.59 could re-use an HTTP request header value from the previous stream received on an HTTP/2 connection for the request associated with the subsequent stream. While this would most likely lead to an error and the closure of the HTTP/2 connection, it is possible that information could leak between requests.

For Debian 9 stretch, this problem has been fixed in version 8.5.54-0+deb9u5.

We recommend that you upgrade your tomcat8 packages.

For the detailed security status of tomcat8 please refer to its security tracker page at:
https://security-tracker.debian.org/tracker/tomcat8

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

Solution

Upgrade the affected packages.
