Synopsis: FEDORA-2013-1965 can now be patched using Ksplice
CVEs: CVE-2013-0268

Systems running Fedora 17 can now use Ksplice to patch against the
latest Fedora kernel update, FEDORA-2013-1965.


We recommend that all users of Ksplice Uptrack on Fedora 17 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


* Use after free on LUN RESET of target driver IO handling driver.

A LUN RESET command during a long backend IO can trigger a use-after-free
on IO completion.

* NULL pointer dereference in Radeon CS parser in UMS mode.

When running in UMS mode the parser might try to dereference the
device pointer, which is NULL in that mode.

* Invalid memory free in Radeon CS parser in UMS mode.

The CS parser in the Radeon driver may attempt to free a memory
which was never dynamically allocated in the first place in
UMS mode.

* NULL pointer dereference in USB Inside Out Edgeport serial driver.

A NULL pointer dereference may occur during disconnection of the driver
due to a missing check.

* Denial-of-service in Extended Verification Module.

A missing NULL pointer check could lead to an NULL pointer dereference
and a kernel oops when removing an extended attribute from a file that
does not implemented extended attributes.  This could allow an
unprivileged user to crash the system.

* User buffer overflow in VFIO.

The VFIO PCI driver could overflow the user buffer with certain read

* Race condition in USB UHCI during initialization.

A race condition exists in the USB UHCI code that could cause the
interrupt handler to be called before all data structures are setup,
leading to potential invalid memory accesses.

* NULL pointer dereference in ACPI with cpuidle disabled.

The ACPI code does not correctly handle all cases where cpuidle is
disabled, leading to a kernel NULL pointer dereference.

* Use-after-free in XFS AIO handling.

An inode reference was released before all operations on it were complete.
This might lead to a use-after-free if the inode was freed.

* Memory leak in ATH9K HTC layer skb allocation.

All SKBs which were allocated by the ATH9K HTC layer were not freed,
causing a memory leak.

* Memory corruption in ATH9K handling to flush command.

DMA activity wasn't stopped when handling a flush command, leading
to a memory corruption.

* Double free on ATH9K beacon generate failure.

An incorrect re-use of objects between beacon generation attempts would
lead to a system crash.

* CVE-2013-0268: /dev/cpu/*/msr local privilege escalation.

Access to /dev/cpu/*/msr was protected only using filesystem
checks. A local uid 0 (root) user with all capabilities dropped
could use this flaw to execute arbitrary code in kernel mode.

* Invalid memory access in KVM IRQFD assignment.

KVM didn't iterate existing irqfd lists correctly, causing access to invalid
areas of the memory and system crashes.
