A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 15.04
- Ubuntu 14.10

Summary:

Aptdaemon could be made to expose sensitive information, or allow file
access as the administrator.

Software Description:

Details:

Tavis Ormandy discovered that Aptdeamon incorrectly handled the simulate
dbus method. A local attacker could use this issue to possibly expose
sensitive information, or perform other file access as the root user.
