CVE-2019-20446: Canonical Ubuntu Linux

Medium severity, CVSS 6.5. EPSS: 2.1% chance of exploitation in the next 30 days.

In xml.rs in GNOME librsvg before 2.46.2, a crafted SVG file with nested patterns can cause denial of service when passed to the library for processing. The attacker constructs pattern elements so that the number of final rendered objects grows exponentially.
