Package : tomcat8
Version : 8.5.54-0+deb9u5
CVE ID : CVE-2020-17527
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
