[Ksplice][Fedora-17-updates] New updates available via Ksplice (FEDORA-2012-12064)

[Sasha Levin]

Synopsis: FEDORA-2012-12064 can now be patched using Ksplice
CVEs: CVE-2012-3412

Systems running Fedora 17 can now use Ksplice to patch against the
latest Fedora kernel update, FEDORA-2012-12064.

INSTALLING THE UPDATES

We recommend that all users of Ksplice Uptrack on Fedora 16 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 qeth driver.

Missing NULL pointer checks could result in a kernel crash and
denial-of-service.


* NULL pointer dereference in non-pi futexes.

Incorrect configuration of futex addresses could lead to a NULL pointer
dereference and kernel crash.


* Kernel stack information leak in tun ioctls.

Incorrect initialization of ioctl structures could result in leaking
stack bytes to a userspace process.


* Use-after-free in tg3 network driver stats.

Invalid locking could result in a use-after-free condition when
accessing device statistics.


* Kernel panic on SUNRPC initialization failure.

A kernel panic may occur due to a failed SUNRPC initialization due to invalid
return values returned by the initialization function.


* NULL pointer dereference in non-persistent tunnel devices.

A NULL pointer dereference in the tunnelling network device may occur
when closing a tunnel device.


* Kernel information leak in put_cmsg_compat().

A networking compatibility handler for 32-bit processes used stack
variables outside of their scope resulting in a kernel stack information
leak to users.
* Memory leak in radeon buffer object management.

Incorrect error handling could result in a memory leak and
denial-of-service.


* Denial of service in hugetlbfs shared page table teardown.

A race condition in hugetlbfs shared page table teardown may cause a corruption
of the pagetables, leading to a kernel BUG.


* Memory leak in device mapper thin provisioning driver.

Incorrect error handling could result in a memory leak and denial of
service.


* NULL pointer dereference in Ralink rt2x00 wireless network driver.

Due to incorrect initialization of a data structure, a NULL pointer
dereference may occur on device wakeup.


* Data loss in ext4 filesystems.

An integer underflow in metadata block management could result in
allocation failure and data loss.


* Kernel crash in radeon DRM driver.

Incorrect error handling in the CS parser could result in a kernel oops
when managing fence buffer objects.


* NULL pointer dereference in futex requeuing.

A missing NULL pointer check could result in a kernel crash when
attempting to requeue a futex.


* CVE-2012-3412: Remote denial of service through TCP MSS option in SFC NIC.

A malicious remote user may trigger a denial-of-service in hosts using the SFC
NIC by reducing the size of the TCP MSS and causing the victim to run out
of resources while processing the packets.


* NULL pointer dereference in caif tty driver.

A missing NULL pointer check could result in a kernel crash when opening
the tty device.
