Debian DLA-2693-1 : xmlbeans - LTS security update

critical Nessus Plugin ID 151111

Language:

Synopsis

The remote Debian host is missing a security-related update.

Description

The remote Debian 9 host has packages installed that are affected by a vulnerability as referenced in the dla-2693 advisory.

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: https://security-tracker.debian.org/tracker/xmlbeans Further information about Debian LTS security advisories, how to apply these updates to your system and frequently asked questions can be found at: https://wiki.debian.org/LTS

Tenable has extracted the preceding description block directly from the Debian security advisory.

Solution

Upgrade the xmlbeans packages.

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