Package : xmlbeans
Version : 2.6.0+dfsg-1+deb9u1
CVE ID : CVE-2021-23926

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.
