An update that solves 14 vulnerabilities and has 8 fixes is
now available.

Description:


The SUSE Linux Enterprise 12 kernel was updated to 3.12.61 to receive
various security and bugfixes.

The following security bugs were fixed:

- CVE-2017-16939: The XFRM dump policy implementation in
net/xfrm/xfrm_user.c in the Linux kernel allowed local users to gain
privileges or cause a denial of service (use-after-free) via a crafted
SO_RCVBUF setsockopt system call in conjunction with XFRM_MSG_GETPOLICY
Netlink messages (bnc#1069702 1069708).
- CVE-2017-1000405: The Linux Kernel had a problematic use of
pmd_mkdirty() in the touch_pmd() function inside the THP implementation.
touch_pmd() could be reached by get_user_pages(). In such case, the pmd
would become dirty. This scenario breaks the new
can_follow_write_pmd()'s logic - pmd could become dirty without going
through a COW cycle. This bug was not as severe as the original "Dirty
cow" because an ext4 file (or any other regular file) could not be
mapped using THP. Nevertheless, it did allow us to overwrite read-only
huge pages. For example, the zero huge page and sealed shmem files could
be overwritten (since their mapping could be populated using THP). Note
that after the first write page-fault to the zero page, it will be
replaced with a new fresh (and zeroed) thp (bnc#1069496 1070307).
- CVE-2017-16649: The usbnet_generic_cdc_bind function in
drivers/net/usb/cdc_ether.c in the Linux kernel allowed local users to
cause a denial of service (divide-by-zero error and system crash) or
possibly have unspecified other impact via a crafted USB device
(bnc#1067085).
- CVE-2014-0038: The compat_sys_recvmmsg function in net/compat.c in the
Linux kernel, when CONFIG_X86_X32 is enabled, allowed local users to
gain privileges via a recvmmsg system call with a crafted timeout
pointer parameter (bnc#860993).
- CVE-2017-16650: The qmi_wwan_bind function in drivers/net/usb/qmi_wwan.c
in the Linux kernel allowed local users to cause a denial of service
(divide-by-zero error and system crash) or possibly have unspecified
other impact via a crafted USB device (bnc#1067086).
- CVE-2017-16535: The usb_get_bos_descriptor function in
drivers/usb/core/config.c in the Linux kernel allowed local users to
cause a denial of service (out-of-bounds read and system crash) or
possibly have unspecified other impact via a crafted USB device
(bnc#1066700).
- CVE-2017-15102: The tower_probe function in
drivers/usb/misc/legousbtower.c in the Linux kernel allowed local users
(who are physically proximate for inserting a crafted USB device) to
gain privileges by leveraging a write-what-where condition that occurs
after a race condition and a NULL pointer dereference (bnc#1066705).
- CVE-2017-16531: drivers/usb/core/config.c in the Linux kernel allowed
local users to cause a denial of service (out-of-bounds read and system
crash) or possibly have unspecified other impact via a crafted USB
device, related to the USB_DT_INTERFACE_ASSOCIATION descriptor
(bnc#1066671).
- CVE-2017-12193: The assoc_array_insert_into_terminal_node function in
lib/assoc_array.c in the Linux kernel mishandled node splitting, which
allowed local users to cause a denial of service (NULL pointer
dereference and panic) via a crafted application, as demonstrated by the
keyring key type, and key addition and link creation operations
(bnc#1066192).
- CVE-2017-16529: The snd_usb_create_streams function in sound/usb/card.c
in the Linux kernel allowed local users to cause a denial of service
(out-of-bounds read and system crash) or possibly have unspecified other
impact via a crafted USB device (bnc#1066650).
- CVE-2017-16525: The usb_serial_console_disconnect function in
drivers/usb/serial/console.c in the Linux kernel allowed local users to
cause a denial of service (use-after-free and system crash) or possibly
have unspecified other impact via a crafted USB device, related to
disconnection and failed setup (bnc#1066618).
- CVE-2017-16537: The imon_probe function in drivers/media/rc/imon.c in
the Linux kernel allowed local users to cause a denial of service (NULL
pointer dereference and system crash) or possibly have unspecified other
impact via a crafted USB device (bnc#1066573).
- CVE-2017-16536: The cx231xx_usb_probe function in
drivers/media/usb/cx231xx/cx231xx-cards.c in the Linux kernel allowed
local users to cause a denial of service (NULL pointer dereference and
system crash) or possibly have unspecified other impact via a crafted
USB device (bnc#1066606).
- CVE-2017-16527: sound/usb/mixer.c in the Linux kernel allowed local
users to cause a denial of service (snd_usb_mixer_interrupt
use-after-free and system crash) or possibly have unspecified other
impact via a crafted USB device (bnc#1066625).
