   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.
