"The XML parsers used by XMLBeans did not set the properties needed to
protect the user from malicious XML input. Vulnerabilities include the
possibility for XML Entity Expansion attacks which could lead to a
denial of service. This update implements sensible defaults for the
XML parsers to prevent these kind of attacks.

For Debian 9 stretch, this problem has been fixed in version
2.6.0+dfsg-1+deb9u1.

We recommend that you upgrade your xmlbeans packages.

For the detailed security status of xmlbeans please refer to its
security tracker page at:

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."
