Ubuntu Security Notice USN-1485-1
June 28, 2012

accountsservice vulnerability

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

- Ubuntu 12.04 LTS
- Ubuntu 11.10


AccountsService could be made to read arbitrary files as the administrator.

Software Description:
- accountsservice: query and manipulate user account information


Florian Weimer discovered that AccountsService incorrectly handled
privileges when copying certain files to the system cache directory. A
local attacker could exploit this issue to read arbitrary files, bypassing
intended permissions.

Update instructions:

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

Ubuntu 12.04 LTS:
  accountsservice                 0.6.15-2ubuntu9.1
  libaccountsservice0             0.6.15-2ubuntu9.1

Ubuntu 11.10:
  accountsservice                 0.6.14-1git1ubuntu1.2
  libaccountsservice0             0.6.14-1git1ubuntu1.2

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