Test ID:
Category:Red Hat Local Security Checks
Title:RedHat Update for system-config-firewall RHSA-2011:0953-01
Summary:The remote host is missing an update for the 'system-config-firewall'; package(s) announced via the referenced advisory.
The remote host is missing an update for the 'system-config-firewall'
package(s) announced via the referenced advisory.

Vulnerability Insight:
system-config-firewall is a graphical user interface for basic firewall

It was found that system-config-firewall used the Python pickle module in
an insecure way when sending data (via D-Bus) to the privileged back-end
mechanism. A local user authorized to configure firewall rules using
system-config-firewall could use this flaw to execute arbitrary code with
root privileges, by sending a specially-crafted serialized object.

Red Hat would like to thank Marco Slaviero of SensePost for reporting this

This erratum updates system-config-firewall to use JSON (JavaScript Object
Notation) for data exchange, instead of pickle. Therefore, an updated
version of system-config-printer that uses this new communication data
format is also provided in this erratum.

Users of system-config-firewall are advised to upgrade to these updated
packages, which contain a backported patch to resolve this issue. Running
instances of system-config-firewall must be restarted before the utility
will be able to communicate with its updated back-end.

Affected Software/OS:
system-config-firewall on Red Hat Enterprise Linux Desktop (v. 6),
Red Hat Enterprise Linux Server (v. 6),
Red Hat Enterprise Linux Workstation (v. 6)

Please Install the Updated Packages.
