An update that solves 10 vulnerabilities and has 25 fixes
is now available.

Description:


The Linux kernel was updated to fix various bugs and
security issues:

CVE-2013-0871: Race condition in the ptrace functionality
in the Linux kernel allowed local users to gain privileges
via a PTRACE_SETREGS ptrace system call in a crafted
application, as demonstrated by ptrace_death.

CVE-2013-0160: Avoid a side channel attack on /dev/ptmx
(keyboard input timing).

CVE-2012-5374: Fixed a local denial of service in the BTRFS
hashing code.

CVE-2013-0309: arch/x86/include/asm/pgtable.h in the Linux
kernel, when transparent huge pages are used, does not
properly support PROT_NONE memory regions, which allows
local users to cause a denial of service (system crash) via
a crafted application.

CVE-2013-0268: The msr_open function in
arch/x86/kernel/msr.c in the Linux kernel allowed local
users to bypass intended capability restrictions by
executing a crafted application as root, as demonstrated by
msr32.c.

CVE-2012-0957: The override_release function in
kernel/sys.c in the Linux kernel allowed local users to
obtain sensitive information from kernel stack memory via a
uname system call in conjunction with a UNAME26 personality.

CVE-2013-0216: The Xen netback functionality in the Linux
kernel allowed guest OS users to cause a denial of service
(loop) by triggering ring pointer corruption.

CVE-2013-0231: The pciback_enable_msi function in the PCI
backend driver
(drivers/xen/pciback/conf_space_capability_msi.c) in Xen
for the Linux kernel allowed guest OS users with PCI device
access to cause a denial of service via a large number of
kernel log messages. NOTE: some of these details are
obtained from third party information.

CVE-2012-4530: The load_script function in
fs/binfmt_script.c in the Linux kernel did not properly
handle recursion, which allowed local users to obtain
sensitive information from kernel stack memory via a
crafted application.

CVE-2012-4508: Race condition in fs/ext4/extents.c in the
Linux kernel allowed local users to obtain sensitive
information from a deleted file by reading an extent that
was not properly marked as uninitialized.

CVE-2012-3412: The sfc (aka Solarflare Solarstorm) driver
in the Linux kernel allowed remote attackers to cause a
denial of service (DMA descriptor consumption and
network-controller outage) via crafted TCP packets that
trigger a small MSS value.

CVE-2012-2745: The copy_creds function in kernel/cred.c in
the Linux kernel provided an invalid replacement session
keyring to a child process, which allowed local users to
cause a denial of service (panic) via a crafted application
that uses the fork system call.

CVE-2012-3375: The epoll_ctl system call in fs/eventpoll.c
in the Linux kernel did not properly handle ELOOP errors in
EPOLL_CTL_ADD operations, which allowed local users to
cause a denial of service (file-descriptor consumption and
system crash) via a crafted application that attempts to
create a circular epoll dependency.

CVE-2012-3400: Heap-based buffer overflow in the
udf_load_logicalvol function in fs/udf/super.c in the Linux
kernel allowed remote attackers to cause a denial of
service (system crash) or possibly have unspecified other
impact via a crafted UDF filesystem.
