    Software Description:
    - librsvg: renderer library for SVG files
    
    Details:
    
    It was discovered that librsvg incorrectly handled parsing certain SVG
    files. A remote attacker could possibly use this issue to cause librsvg to

    It was discovered that librsvg incorrectly handled parsing certain SVG
    files with nested patterns. A remote attacker could possibly use this issue
    to cause librsvg to consume resources and crash, resulting in a denial of
    service. (CVE-2019-20446)
    
    Update instructions:
    
    The problem can be corrected by updating your system to the following
    package versions:

      librsvg2-2                      2.40.20-2ubuntu0.1
    
    Ubuntu 16.04 LTS:
      librsvg2-2                      2.40.13-3ubuntu0.1
    
    After a standard system update you need to restart your session to make all
    the necessary changes.
