______________________________________________________________________________
An update that fixes 8 vulnerabilities is now available.
Description:
This update for tomcat to version 8.0.53 fixes the following security
issues:
- CVE-2018-11784: When the default servlet in Apache Tomcat returned a
redirect to a directory (e.g. redirecting to '/foo/' when the user
requested '/foo') a specially crafted URL could be used to cause the
redirect to be generated to any URI of the attackers choice.
(bsc#1110850)
- 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-2018-1305: Fixed late application of security constraints that can
lead to resource exposure for unauthorised users (bsc#1082481).
- CVE-2018-1304: Fixed incorrect handling of empty string URL in security
constraints that can lead to unitended exposure of resources
(bsc#1082480).
- CVE-2017-15706: Fixed incorrect documentation of CGI Servlet search
algorithm that may lead to misconfiguration (bsc#1078677).
- CVE-2018-8014: The defaults settings for the CORS filter were insecure
and enable 'supportsCredentials' for all origins (bsc#1093697).
