Synopsis
========

rclone uses weak random number generation such that generated passwords
can be easily cracked.

Background
==========

rclone is a problem to sync files to and from various cloud storage
providers.

Affected packages
=================

    -------------------------------------------------------------------
     Package              /     Vulnerable     /            Unaffected

Description
===========

Passwords generated with rclone were insecurely generated and are
vulnerable to brute force attacks.

Impact
======

Data kept secret with a password generated by rclone may be disclosed
to a local attacker.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All rclone users should upgrade to the latest version:

  # emerge --sync
  # emerge --ask --oneshot --verbose ">=net-misc/rclone-1.53.3"
