Synopsis
========

A command injection vulnerability in 'Back in Time' may allow for the
execution of arbitrary shell commands.

==========

A simple backup tool for Linux, inspired by "flyback project".

Affected packages

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

'Back in Time' did improper escaping/quoting of file paths used as
arguments to the 'notify-send' command leading to some parts of file
paths being executed as shell commands within an os.system call.

Impact

a specially crafted file.

Workaround
==========

There is no known workaround at this time.
