USN-2648-1: Aptdaemon vulnerability

16 June 2015

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



  • aptdaemon - transaction based package management service


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.

Update instructions

The problem can be corrected by updating your system to the following package versions:

Ubuntu 15.04
Ubuntu 14.10
Ubuntu 14.04
Ubuntu 12.04

After a standard system update you need to reboot your computer to make
all the necessary changes.
