June 28, 2012

accountsservice vulnerability
==========================================================================

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

- Ubuntu 11.10

Summary:

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

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

Details:

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.

package versions:

Ubuntu 12.04 LTS:

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