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:

  o 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.

    elements, through nested use of SVG "use" elements in malicious SVGs.
