  script_tag(name:"insight", value:"Updated tomcat packages fix security vulnerabilities:

The HTTP/2 implementation accepted streams with excessive numbers of
SETTINGS frames and also permitted clients to keep streams open without
reading/writing request/response data. By keeping streams open for
requests that utilised the Servlet API's blocking I/O, clients were able
to cause server-side threads to block eventually leading to thread
exhaustion and a DoS (CVE-2019-0199).

The SSI printenv command echoes user provided data without escaping and
is, therefore, vulnerable to XSS. SSI is disabled by default. The printenv
command is intended for debugging and is unlikely to be present in a
production website (CVE-2019-0221).

The fix for CVE-2019-0199 was incomplete and did not address HTTP/2
connection window exhaustion on write. 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).

The tomcat package has been updated to version 9.0.21 to fix these issues.
The tomcat-native package has also been updated to version 1.2.23.");
