Echo: xdg-utils: security update to 1.2.1-2+e1

medium Tenable Self-Hosted Container Security Plugin ID 459294

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - A flaw was found in the xdg-email component of xdg-utils-1.1.0-rc1 and newer. When handling mailto: URIs,
 xdg-email allows attachments to be discreetly added via the URI when being passed to Thunderbird. An
 attacker could potentially send a victim a URI that automatically attaches a sensitive file to a new
 email. If a victim user does not notice that an attachment was added and sends the email, this could
 result in sensitive information disclosure. It has been confirmed that the code behind this issue is in
 xdg-email and not in Thunderbird. (CVE-2020-27748)

Solution

Update the xdg-utils library and its related packages to version 1.2.1-2+e1 or later.
