Description
A race condition flaw was found in the PolicyKit pkexec utility and polkitd
daemon. A local user could use this flaw to appear as a privileged user to
pkexec, allowing them to execute arbitrary commands as root by running
those commands with pkexec.
Those vulnerable include RHEL6 prior to polkit-0.96-2.el6_0.1 and Ubuntu
libpolkit-backend-1 prior to 0.96-2ubuntu1.1 (10.10) 0.96-2ubuntu0.1
(10.04 LTS) and 0.94-1ubuntu1.1 (9.10)
daemon. A local user could use this flaw to appear as a privileged user to
pkexec, allowing them to execute arbitrary commands as root by running
those commands with pkexec.
