| Description: | NetworkManager is a network link manager that attempts to keep a wired or wireless network connection active at all times. The ifcfg-rh NetworkManager plug-in is used in Red Hat Enterprise Linux distributions to read and write configuration information from the /etc/sysconfig/network-scripts/ifcfg-files.
An input sanitization flaw was found in the way the ifcfg-rh NetworkManager plug-in escaped network connection names containing special characters. If PolicyKit was configured to allow local, unprivileged users to create and save new network connections, they could create a connection with a specially-crafted name, leading to the escalation of their privileges. Note: By default, PolicyKit prevents unprivileged users from creating and saving network connections. (CVE-2011-3364)
Red Hat would like to thank Matt McCutchen for reporting this issue.
Users of NetworkManager should upgrade to these updated packages, which contain a backported patch to correct this issue. Running instances of NetworkManager must be restarted ("service NetworkManager restart") for this update to take effect.
