The Ubuntu security team deemed this advisory irrelevant for Ubuntu:19.10.
NVD Description
Note: Versions mentioned in the description apply only to the upstream evolution package and not the evolution package as distributed by Ubuntu.
An issue was discovered in GNOME Evolution before 3.35.91. By using the proprietary (non-RFC6068) "mailto?attach=..." parameter, a website (or other source of mailto links) can make Evolution attach local files or directories to a composed email message without showing a warning to the user, as demonstrated by an attach=. value.
