   An update that solves four vulnerabilities and has two
   fixes is now available.

Description:

   This update for tomcat to 8.0.53 fixes the following issues:

   Security issue fixed:

   - CVE-2018-1336: An improper handing of overflow in the UTF-8 decoder with
     supplementary characters could have lead to an infinite loop in the
     decoder causing a Denial of Service (bsc#1102400).
   - CVE-2018-8034: The host name verification when using TLS with the
     WebSocket client was missing. It is now enabled by default (bsc#1102379).
   - CVE-2018-8037: If an async request was completed by the application at
     the same time as the container triggered the async timeout, a race
     condition existed that could have resulted in a user seeing a response
     intended for a different user. An additional issue was present in the
     NIO and NIO2 connectors that did not correctly track the closure of the
     connection when an async request was completed by the application and
     timed out by the container at the same time. This could also have
     resulted in a user seeing a response intended for another user
     (bsc#1102410).
   - CVE-2018-8014: Fix insecure default CORS filter settings (bsc#1093697).

   Bug fixes:

   - bsc#1067720: Avoid overwriting of customer's configuration during update.
   - bsc#1095472: Add Obsoletes for tomcat6 packages.
