Título:	RedHat Update for system-config-firewall RHSA-2011:0953-01
Resumen:	The remote host is missing an update for the 'system-config-firewall'; package(s) announced via the referenced advisory.
Descripción:	Summary: 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 setup. 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. (CVE-2011-2520) Red Hat would like to thank Marco Slaviero of SensePost for reporting this issue. 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) Solution: Please Install the Updated Packages. CVSS Score: 6.0 CVSS Vector: AV:L/AC:H/Au:S/C:C/I:C/A:C
