"Security researchers from Snyk discovered that the fix for
CVE-2019-9658 was incomplete. Checkstyle, a development tool to help
programmers write Java code that adheres to a coding standard, was
still vulnerable to XML External Entity (XXE) injection.

For Debian 8 'Jessie', this problem has been fixed in version
5.9-1+deb8u2.

We recommend that you upgrade your checkstyle packages.

NOTE: Tenable Network Security has extracted the preceding description
block directly from the DLA security advisory. Tenable has attempted
to automatically clean and format it as much as possible without
introducing additional issues."
