[Ksplice-Fedora-19-updates] New updates available via Ksplice (FEDORA-2013-15545)

[Oracle Ksplice]

Synopsis: FEDORA-2013-15545 can now be patched using Ksplice

Systems running Fedora 19 can now use Ksplice to patch against the
latest Fedora kernel update, FEDORA-2013-15545.

INSTALLING THE UPDATES

We recommend that all users of Ksplice Uptrack on Fedora 19 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

* NULL pointer dereference in VFS auditing.

The kernel auditing subsystem incorrectly validates a pointer when processing
audit messages leading to a NULL pointer dereference and kernel panic.


* NULL pointer dereference in comedi device initialization.

The kernel can dereference a NULL pointer when failing to initialize a comedi
device leading to a kernel panic.


* Deadlock in NILFS2 segment buffer processing.

Incorrect reference counting in the NILFS2 filesystem driver when processing
segment buffers can trigger a deadlock causing a kernel panic.


* User memory corruption in SCSI SG_IO ioctl.

If a process performing a SG_IO ioctl on a SCSI device is interrupted by a signal,
the kernel may continue the ioctl in the address space of another process leading
to memory corruption.


* NULL pointer dereference in bcache buffer allocation.

The kernel does not correctly handle a failed memory allocation when handling
buffers in a block cache device leading to a NULL pointer dereference and kernel
panic.


* Improved fix for 'Unlimited stack ASLR bypass on 64-bit systems'.

The original update for 'Unlimited stack ASLR bypass on 64-bit systems' did not
correctly handle randomising the stack causing compatibility issues with some
existing user-mode programs. This update corrects the issue.
