NVD Description

Note: Versions mentioned in the description apply only to the upstream xdg-utils package and not the xdg-utils package as distributed by Echo. See How to fix? for Echo:latest relevant fixed versions and status.

When xdg-mail is configured to use thunderbird for mailto URLs, improper parsing of the URL can lead to additional headers being passed to thunderbird that should not be included per RFC 2368. An attacker can use this method to create a mailto URL that looks safe to users, but will actually attach files when clicked.
