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

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).

Use-after-free vulnerability in the skb_segment function in
net/core/skbuff.c in the Linux kernel through 3.13.6 allows attackers
to obtain sensitive information from kernel memory by leveraging the
absence of a certain orphaning operation (CVE-2014-0131).

The rd_build_device_space function in drivers/target/target_core_rd.c
in the Linux kernel before 3.14 does not properly initialize a certain
data structure, which allows local users to obtain sensitive
information from ramdisk_mcp memory by leveraging access to a SCSI
initiator (CVE-2014-4027).

Multiple integer overflows in the lzo1x_decompress_safe function in
lib/lzo/lzo1x_decompress_safe.c in the LZO decompressor in the Linux
kernel before 3.15.2 allow context-dependent attackers to cause a
denial of service (memory corruption) via a crafted Literal Run
(CVE-2014-4608).

Race condition in the tlv handler functionality in the
snd_ctl_elem_user_tlv function in sound/core/control.c in the ALSA
control implementation in the Linux kernel before 3.15.2 allows local
users to obtain sensitive information from kernel memory by leveraging
/dev/snd/controlCX access (CVE-2014-4652).

sound/core/control.c in the ALSA control implementation in the Linux
kernel before 3.15.2 does not ensure possession of a read/write lock,
which allows local users to cause a denial of service (use-after-free)
and obtain sensitive information from kernel memory by leveraging
/dev/snd/controlCX access (CVE-2014-4653).

The snd_ctl_elem_add function in sound/core/control.c in the ALSA
control implementation in the Linux kernel before 3.15.2 does not
check authorization for SNDRV_CTL_IOCTL_ELEM_REPLACE commands, which
allows local users to remove kernel controls and cause a denial of
service (use-after-free and system crash) by leveraging
/dev/snd/controlCX access for an ioctl call (CVE-2014-4654).

The snd_ctl_elem_add function in sound/core/control.c in the ALSA
control implementation in the Linux kernel before 3.15.2 does not
properly maintain the user_ctl_count value, which allows local users
to cause a denial of service (integer overflow and limit bypass) by
leveraging /dev/snd/controlCX access for a large number of
SNDRV_CTL_IOCTL_ELEM_REPLACE ioctl calls (CVE-2014-4655).

Multiple integer overflows in sound/core/control.c in the ALSA control
implementation in the Linux kernel before 3.15.2 allow local users to
cause a denial of service by leveraging /dev/snd/controlCX access,
related to (1) index values in the snd_ctl_add function and (2) numid
values in the snd_ctl_remove_numid_conflict function (CVE-2014-4656).

The sctp_association_free function in net/sctp/associola.c in the
Linux kernel before 3.15.2 does not properly manage a certain backlog
value, which allows remote attackers to cause a denial of service
(socket outage) via a crafted SCTP packet (CVE-2014-4667).

The Linux kernel before 3.15.4 on Intel processors does not properly
restrict use of a non-canonical value for the saved RIP address in the
case of a system call that does not use IRET, which allows local users
to leverage a race condition and gain privileges, or cause a denial of
service (double fault), via a crafted application that makes ptrace
and fork system calls (CVE-2014-4699).

The PPPoL2TP feature in net/l2tp/l2tp_ppp.c in the Linux kernel
through 3.15.6 allows local users to gain privileges by leveraging
data-structure differences between an l2tp socket and an inet socket
(CVE-2014-4943).

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