Description:

This update for librsvg to version 2.42.8 fixes the following issues:

librsvg was updated to version 2.42.8 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.
- Fixed a denial-of-service condition from exponential explosion
of rendered elements, through nested use of SVG "use" elements in
malicious SVGs.
