Updated tomcat packages fix security vulnerabilities

Publication date: 28 Feb 2018
Type: security
Affected Mageia releases : 6
CVE: CVE-2017-15706 , CVE-2018-1304 , CVE-2018-1305


In Tomcat 8.0.45, the description of the search algorithm used by the
CGI Servlet to identify which script to execute was updated. The update
was not correct. As a result, some scripts may have failed to execute as
expected and other scripts may have been executed unexpectedly. Note
that the behavior of the CGI servlet has remained unchanged in this
regard. It is only the documentation of the behavior that was wrong and
has been corrected (CVE-2017-15706).

The URL pattern of "" (the empty string) which exactly maps to the
context root was not correctly handled when used as part of a
security constraint definition. This caused the constraint to be ignored.
It was, therefore, possible for unauthorized users to gain access to web
application resources that should have been protected. Only security
constraints with a URL pattern of the empty string were affected

Security constraints defined by annotations of Servlets were only
applied once a Servlet had been loaded. Because security constraints
defined in this way apply to the URL pattern and any URLs below that
point, it was possible - depending on the order Servlets were loaded -
for some security constraints not to be applied. This could have exposed
resources to users who were not authorized to access them
