* A flaw was found in the way the pppol2tp_setsockopt() and
pppol2tp_getsockopt() functions in the Linux kernel's PPP over L2TP
implementation handled requests with a non-SOL_PPPOL2TP socket option
level. A local, unprivileged user could use this flaw to escalate
their privileges on the system. (CVE-2014-4943, Important)
Red Hat would like to thank Sasha Levin for reporting this issue.
This update also fixes the following bug :
* When a device was registered to a bus, a race condition could occur
between the device being added to the list of devices of the bus and
binding the device to a driver. As a result, the device could already
be bound to a driver which led to a warning and incorrect reference
counting, and consequently to a kernel panic on device removal. To
avoid the race condition, this update adds a check to identify an
already bound device. (BZ#1114409)
All kernel users are advised to upgrade to these updated packages,
which contain backported patches to correct these issues. The system
must be rebooted for this update to take effect.
