Description

NetworkManager is a network link manager that attempts to keep a wired orwireless network connection active at all times. The ifcfg-rhNetworkManager plug-in is used in Red Hat Enterprise Linux distributions toread and write configuration information from the/etc/sysconfig/network-scripts/ifcfg-* files.An input sanitization flaw was found in the way the ifcfg-rh NetworkManagerplug-in escaped network connection names containing special characters. IfPolicyKit was configured to allow local, unprivileged users to create andsave new network connections, they could create a connection with aspecially-crafted name, leading to the escalation of their privileges.Note: By default, PolicyKit prevents unprivileged users from creating andsaving 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, whichcontain a backported patch to correct this issue. Running instances ofNetworkManager must be restarted ("service NetworkManager restart") forthis update to take effect.
