-----------------------------------
Summary: Upgrade all test XML doctypes
Key: MCHECKSTYLE-375
URL: https://issues.apache.org/jira/browse/MCHECKSTYLE-375
Project: Maven Checkstyle Plugin
Issue Type: Improvement
Components: checkstyle:check, checkstyle:checkstyle
Affects Versions: 3.0.0
Reporter: richard
The tests used to test maven-checkstyle are using old DTDs and unsecure "http"
locations. This is related to CVE-2019-9658. The security issue is in the
parser that is used to parse this file. It leaves any code that parses this
file vulnerable to XXE via a MITM.
All doctypes used in maven-checkstyle repo (configurations, suppressions,
import controls, etc...) should be updated to use the latest URL and public
DOCTYPEs.
Example:
````
<!DOCTYPE module PUBLIC
"-//Checkstyle//DTD Checkstyle Configuration 1.3//EN"
"https://checkstyle.org/dtds/configuration_1_3.dtd";>
````
