librsvg was updated to version 2.40.21 fixing the following issues :

CVE-2019-20446: Fixed an issue where a crafted SVG file with nested patterns can cause denial of service (bsc#1162501). NOTE: Librsvg now has limits on the number of loaded XML elements, and the number of referenced elements within an SVG document.

Fixed a stack exhaustion with circular references in <use> elements.
</use>

Fixed a denial-of-service condition from exponential explosion of rendered elements, through nested use of SVG 'use' elements in malicious SVGs.

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