[Ksplice][Fedora-18-updates] New updates available via Ksplice (FEDORA-2013-6041)

[Phil Turnbull]

Synopsis: FEDORA-2013-6041 can now be patched using Ksplice

Systems running Fedora 18 can now use Ksplice to patch against the
latest Fedora kernel update, FEDORA-2013-6041.

INSTALLING THE UPDATES

We recommend that all users of Ksplice Uptrack on Fedora 18 install
these updates.

On systems that have "autoinstall = yes" in /etc/uptrack/uptrack.conf,
these updates will be installed automatically and you do not need to
take any action.

Alternatively, you can install these updates by running:

# /usr/sbin/uptrack-upgrade -y


DESCRIPTION

* Memory corruption in receiving IPC messages.

The local IPC mechanism in the kernel incorrectly frees an invalid
pointer when failing to receive a message leading to memory corruption
and a kernel panic.


* Kernel panic in GFS2 file locking.

Attempting to lock a remote file on a GFS2 cluster that has been
withdrawn can trigger an assertion failure and kernel panic.


* NULL pointer dereference in GFS2 resource group.

The GFS2 filesystem does not correctly handle failing to allocate a new
resource group leading to a NULL pointer dereference and kernel panic.


* Use-after-free in kernel module loading.

A race condition in the kobject subsystem can cause a use-after-free
condition and kernel panic when loading kernel modules.


* Deadlock in TTY workqueue flushing.

Invalid locking in the TTY subsystem can lead to a deadlock and kernel
panic when flushing the TTY workqueue.
