QID 983088: Python (pip) Security Update for feedgen (GHSA-g8q7-xv52-hf9f)

Security update has been released for feedgen to fix the vulnerability.

Note: The preceding description block is extracted directly from the security advisory. Using automation, we have attempted to clean and format it as much as possible without introducing additional issues.

The *feedgen* library allows supplying XML as content for some of the available fields. This XML will be parsed and integrated into the existing XML tree. During this process, feedgen is vulnerable to [XML Denial of Service Attacks](https://docs.microsoft.com/en-us/archive/msdn-magazine/2009/november/xml-denial-of-service-attacks-and-defenses) (e.g. XML Bomb).

This becomes a concern in particular if feedgen is used to include content from untrused sources and if XML (including XHTML) is directly included instead of providing plain tex content only.

CVSS V3 rated as High - 7.5 severity.

CVSS V2 rated as Medium - 5 severity.

Solution

This problem has been fixed in feedgen 0.9.0 which disallows XML entity expansion and external resources.Workaround:
Updating is strongly recommended and should not be problematic. Nevertheless, as a workaround, avoid providing XML directly to feedgen or ensure that no entity expansion is part of the XML.
