You can use "apt-cache policy", for example. This way you can see the current installed version of a package in your system, and also if there's a newer version you can install (the candidate). $ apt-cache policy accountsservice accountsservice: Installed: 0.6.40-2ubuntu11.6 Candidate: 0.6.40-2ubuntu11.6 If the installed version reported by the utility is the version that Ubuntu states the problem has been fixed for your release, then presumably your system is safe (for this bug).
