Package        : tomcat7
Version        : 7.0.28-4+deb7u18
CVE ID         : CVE-2018-1304 CVE-2018-1305

Two security vulnerabilities have been discovered in the Tomcat
servlet and JSP engine.

CVE-2018-1304
    The URL pattern of "" (the empty string) which exactly maps to the
    context root was not correctly handled in Apache Tomcat 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.

CVE-2018-1305
    Security constraints defined by annotations of Servlets in Apache
    Tomcat 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.

For Debian 7 "Wheezy", these problems have been fixed in version
7.0.28-4+deb7u18.

We recommend that you upgrade your tomcat7 packages.
