The remote host is affected by the vulnerability described in GLSA-201801-06 (Back In Time: Command injection)
‘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 context-dependent attacker could execute arbitrary shell commands via a specially crafted file.
Workaround :
There is no known workaround at this time.
