Back in Time: CVE-2017-16667: shell injection in notify-send

[Salvatore Bonaccorso <carnil () debian org>]

Hi

MITRE has assinged CVE-2017-16667 for the following isue in Back in
Time, "a simple backup tool for Linux". backintime is prone to a shell
injection vulnerability via notify-sent.

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.

An attacker could take advantage of this flaw by crafting an
unreadable file with a specific name to run arbitrary shell commands.
