currently 3.10.24 and fixes the following security issues:

The ipv6_create_tempaddr function in net/ipv6/addrconf.c in the Linux
kernel through 3.10 does not properly handle problems with the generation
of IPv6 temporary addresses, which allows remote attackers to cause a
denial of service (excessive retries and address-generation outage), and
consequently obtain sensitive information, via ICMPv6 Router Advertisement
(RA) messages. (CVE-2013-0343)

net/ceph/auth_none.c in the Linux kernel through 3.10 allows remote
attackers to cause a denial of service (NULL pointer dereference and
system crash) or possibly have unspecified other impact via an auth_reply
message that triggers an attempted build_request operation.
(CVE-2013-1059)

The dispatch_discard_io function in drivers/block/xen-blkback/blkback.c in
the Xen blkback implementation in the Linux kernel before 3.10.5 allows
guest OS users to cause a denial of service (data loss) via filesystem
write operations on a read-only disk that supports the (1) 
BLKIF_OP_DISCARD (aka discard or TRIM) or (2) SCSI UNMAP feature.
(CVE-2013-2140)

The HP Smart Array controller disk-array driver and Compaq SMART2
controller disk-array driver in the Linux kernel through 3.9.4 do not
initialize certain data structures, which allows local users to obtain
sensitive information from kernel memory via (1) a crafted IDAGETPCIINFO
command for a /dev/ida device, related to the ida_locked_ioctl function in
drivers/block/cpqarray.c or (2) a crafted CCISS_PASSTHRU32 command for a
/dev/cciss device, related to the cciss_ioctl32_passthru function in
drivers/block/cciss.c. (CVE-2013-2147)

Format string vulnerability in the register_disk function in block/genhd.c
in the Linux kernel through 3.9.4 allows local users to gain privileges by
leveraging root access and writing format string specifiers to
/sys/module/md_mod/parameters/new_array in order to create a crafted
/dev/md device name. (CVE-2013-2851)

Linux kernel through 3.12 allows remote attackers to cause a denial
of service (infinite loop) via a small value in the IHL field of a
packet with IPIP encapsulation (CVE-2013-4348).

The IPv6 SCTP implementation in net/sctp/ipv6.c in the Linux kernel
through 3.11.1 uses data structures and function calls that do not
trigger an intended configuration of IPsec encryption, which allows
remote attackers to obtain sensitive information by sniffing the
network (CVE-2013-4350).

net/ipv6/ip6_output.c in the Linux kernel through 3.11.4 does not
properly determine the need for UDP Fragmentation Offload (UFO)
processing of small packets after the UFO queueing of a large packet,
which allows remote attackers to cause a denial of service (memory
corruption and system crash) or possibly have unspecified other
impact via network traffic that triggers a large response packet
(CVE-2013-4387).

The Linux kernel before 3.12, when UDP Fragmentation Offload (UFO) is
enabled, does not properly initialize certain data structures, which
allows local users to cause a denial of service (memory corruption and
system crash) or possibly gain privileges via a crafted application
that uses the UDP_CORK option in a setsockopt system call and
sends both short and long packets, related to the ip_ufo_append_data
function in net/ipv4/ip_output.c and the ip6_ufo_append_data function
in net/ipv6/ip6_output.c (CVE-2013-4470).

Buffer overflow in the oz_cdev_write function in
drivers/staging/ozwpan/ozcdev.c in the Linux kernel before 3.12 allows

in the Linux kernel through 3.12.1 allows local users to cause a denial of
service (OOPS) by leveraging root privileges for a zero-length write
operation. (CVE-2013-6378)

The aac_send_raw_srb function in drivers/scsi/aacraid/commctrl.c in the
Linux kernel through 3.12.1 does not properly validate a certain size
value, which allows local users to cause a denial of service (invalid
pointer dereference) or possibly have unspecified other impact via an
FSACTL_SEND_RAW_SRB ioctl call that triggers a crafted SRB command.
(CVE-2013-6380)

Buffer overflow in the qeth_snmp_command function in 
drivers/s390/net/qeth_core_main.c in the Linux kernel through 3.12.1
allows local users to cause a denial of service or possibly have
unspecified other impact via an  SNMP ioctl call with a length value that
is incompatible with the command-buffer size. (CVE-2013-6381)

Multiple buffer underflows in the XFS implementation in the Linux kernel
through 3.12.1 allow local users to cause a denial of service (memory
corruption) or possibly have unspecified other impact by leveraging the
CAP_SYS_ADMIN capability for a (1) XFS_IOC_ATTRLIST_BY_HANDLE or (2)
XFS_IOC_ATTRLIST_BY_HANDLE_32 ioctl call with a crafted length value,
related to the xfs_attrlist_by_handle function in fs/xfs/xfs_ioctl.c
and the xfs_compat_attrlist_by_handle function in fs/xfs/xfs_ioctl32.c.
(CVE-2013-6382)

The aac_compat_ioctl function in drivers/scsi/aacraid/linit.c in the Linux
kernel before 3.11.8 does not require the CAP_SYS_RAWIO capability, which
