Test ID:
Category:Red Hat Local Security Checks
Title:RedHat Security Advisory RHSA-2012:0517
The remote host is missing updates announced in
advisory RHSA-2012:0517.

The kernel packages contain the Linux kernel, the core of any Linux
operating system.

This update fixes the following security issue:

* A flaw was found in the Linux kernel in the way splitting two extents in
ext4_ext_convert_to_initialized() worked. A local, unprivileged user with
the ability to mount and unmount ext4 file systems could use this flaw to
cause a denial of service. (CVE-2011-3638, Moderate)

Red Hat would like to thank Zheng Liu for reporting this issue.

This update also fixes the following bug:

* Starting with Red Hat Enterprise Linux 5.6, all devices that used the
ixgbe driver would stop stripping VLAN tags when the device entered
promiscuous mode. Placing a device in a bridge group causes the device to
enter promiscuous mode. This caused various issues under certain
configurations of bridging and VLANs. A patch has been provided to address
this issue and the devices now properly strip VLAN tags in the driver
whether in promiscuous mode or not. (BZ#809790)

Users should upgrade to these updated packages, which contain backported
patches to correct these issues. The system must be rebooted for this
update to take effect.

Please note that this update is available via
Red Hat Network. To use Red Hat Network, launch the Red
Hat Update Agent with the following command: up2date
