"Multiple vulnerabilities has been found and corrected in the Linux
kernel :

The Linux kernel before 3.12.2 does not properly use the get_dumpable
function, which allows local users to bypass intended ptrace
restrictions or obtain sensitive information from IA64 scratch
registers via a crafted application, related to kernel/ptrace.c and
arch/ia64/include/asm/processor.h (CVE-2013-2929).

The perf_trace_event_perm function in kernel/trace/trace_event_perf.c
in the Linux kernel before 3.12.2 does not properly restrict access to
the perf subsystem, which allows local users to enable function
tracing via a crafted application (CVE-2013-2930).

Multiple integer overflows in Alchemy LCD frame-buffer drivers in the
Linux kernel before 3.12 allow local users to create a read-write
memory mapping for the entirety of kernel memory, and consequently
gain privileges, via crafted mmap operations, related to the (1)
au1100fb_fb_mmap function in drivers/video/au1100fb.c and the (2)
au1200fb_fb_mmap function in drivers/video/au1200fb.c (CVE-2013-4511).

Buffer overflow in the exitcode_proc_write function in
arch/um/kernel/exitcode.c in the Linux kernel before 3.12 allows local
users to cause a denial of service or possibly have unspecified other
impact by leveraging root privileges for a write operation
(CVE-2013-4512).

Multiple buffer overflows in drivers/staging/wlags49_h2/wl_priv.c in
the Linux kernel before 3.12 allow local users to cause a denial of
service or possibly have unspecified other impact by leveraging the
CAP_NET_ADMIN capability and providing a long station-name string,
related to the (1) wvlan_uil_put_info and (2)
wvlan_set_station_nickname functions (CVE-2013-4514).

The bcm_char_ioctl function in drivers/staging/bcm/Bcmchar.c in the
Linux kernel before 3.12 does not initialize a certain data structure,
which allows local users to obtain sensitive information from kernel
memory via an IOCTL_BCM_GET_DEVICE_DRIVER_INFO ioctl call
(CVE-2013-4515).

Memory leak in the __kvm_set_memory_region function in
virt/kvm/kvm_main.c in the Linux kernel before 3.9 allows local users
to cause a denial of service (memory consumption) by leveraging
certain device access to trigger movement of memory slots
(CVE-2013-4592).

The lbs_debugfs_write function in
drivers/net/wireless/libertas/debugfs.c 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).

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 allows local users to bypass intended access
restrictions via a crafted ioctl call (CVE-2013-6383).

The uio_mmap_physical function in drivers/uio/uio.c in the Linux
kernel before 3.12 does not validate the size of a memory block, which
allows local users to cause a denial of service (memory corruption) or
possibly gain privileges via crafted mmap operations, a different
vulnerability than CVE-2013-4511 (CVE-2013-6763).

The updated packages provides a solution for these security issues."
