______________________________________________________________________________
An update that solves 49 vulnerabilities and has two fixes
is now available.
Description:
The SUSE Linux Enterprise 12 SP2 kernel was updated to receive various
security and bugfixes.
The following security bugs were fixed:
- CVE-2018-12207: Untrusted virtual machines on Intel CPUs could exploit a
race condition in the Instruction Fetch Unit of the Intel CPU to cause a
Machine Exception during Page Size Change, causing the CPU core to be
non-functional.
The Linux Kernel kvm hypervisor was adjusted to avoid page size changes
in executable pages by splitting / merging huge pages into small pages as
needed. More information can be found on
https://www.suse.com/support/kb/doc/?id=7023735
- CVE-2019-16995: Fix a memory leak in hsr_dev_finalize() if hsr_add_port
failed to add a port, which may have caused denial of service
(bsc#1152685).
- CVE-2019-11135: Aborting an asynchronous TSX operation on Intel CPUs
with Transactional Memory support could be used to facilitate
sidechannel information leaks out of microarchitectural buffers, similar
to the previously described "Microarchitectural Data Sampling" attack.
The Linux kernel was supplemented with the option to disable TSX
operation altogether (requiring CPU Microcode updates on older systems)
and better flushing of microarchitectural buffers (VERW).
The set of options available is described in our TID at
https://www.suse.com/support/kb/doc/?id=7024251
- CVE-2019-16233: drivers/scsi/qla2xxx/qla_os.c did not check the
alloc_workqueue return value, leading to a NULL pointer dereference.
(bsc#1150457).
- CVE-2019-10220: Added sanity checks on the pathnames passed to the user
space. (bsc#1144903).
- CVE-2019-17666: rtlwifi: Fix potential overflow in P2P code
(bsc#1154372).
- CVE-2019-17133: cfg80211 wireless extension did not reject a long SSID
IE, leading to a Buffer Overflow (bsc#1153158).
- CVE-2019-16232: Fix a potential NULL pointer dereference in the Marwell
libertas driver (bsc#1150465).
- CVE-2019-16234: iwlwifi pcie driver did not check the alloc_workqueue
return value, leading to a NULL pointer dereference. (bsc#1150452).
- CVE-2019-17055: The AF_ISDN network module in the Linux kernel did not
enforce CAP_NET_RAW, which meant that unprivileged users could create a
raw socket (bnc#1152782).
- CVE-2019-17056: The AF_NFC network module did not enforce CAP_NET_RAW,
which meant that unprivileged users could create a raw socket
(bsc#1152788).
- CVE-2019-16413: The 9p filesystem did not protect i_size_write()
properly, which caused an i_size_read() infinite loop and denial of
service on SMP systems (bnc#1151347).
- CVE-2019-15902: A backporting issue was discovered that re-introduced
the Spectre vulnerability it had aimed to eliminate. This occurred
because the backport process depends on cherry picking specific commits,
and because two (correctly ordered) code lines were swapped
(bnc#1149376).
- CVE-2019-15291: Fixed a NULL pointer dereference issue that could be
caused by a malicious USB device (bnc#1146519).
- CVE-2019-15807: Fixed a memory leak in the SCSI module that could be
abused to cause denial of service (bnc#1148938).
- CVE-2019-13272: Fixed a mishandled the recording of the credentials of a
process that wants to create a ptrace relationship, which allowed local
users to obtain root access by leveraging certain scenarios with a
parent-child process relationship, where a parent drops privileges and
calls execve (potentially allowing control by an attacker).
(bnc#1140671).
- CVE-2019-14821: An out-of-bounds access issue was fixed in the kernel's
kvm hypervisor. An unprivileged host user or process with access to
'/dev/kvm' device could use this flaw to crash the host kernel,
resulting in a denial of service or potentially escalating privileges on
the system (bnc#1151350).
- CVE-2019-15505: An out-of-bounds issue had been fixed that could be
caused by crafted USB device traffic (bnc#1147122).
- CVE-2017-18595: A double free in allocate_trace_buffer was fixed
(bnc#1149555).
- CVE-2019-14835: A buffer overflow flaw was found in the kernel's vhost
functionality that translates virtqueue buffers to IOVs. A privileged
guest user able to pass descriptors with invalid length to the host
could use this flaw to increase their privileges on the host
(bnc#1150112).
- CVE-2019-15216: A NULL pointer dereference was fixed that could be
malicious USB device (bnc#1146361).
- CVE-2019-15924: A a NULL pointer dereference has been fixed in the
drivers/net/ethernet/intel/fm10k module (bnc#1149612).
- CVE-2019-9456: An out-of-bounds write in the USB monitor driver has been
fixed. This issue could lead to local escalation of privilege with
System execution privileges needed. (bnc#1150025).
- CVE-2019-15926: An out-of-bounds access was fixed in the
drivers/net/wireless/ath/ath6kl module. (bnc#1149527).
- CVE-2019-15927: An out-of-bounds access was fixed in the sound/usb/mixer
module (bnc#1149522).
- CVE-2019-15666: There was an out-of-bounds array access in the net/xfrm
module that could cause denial of service (bnc#1148394).
- CVE-2019-15219: A NULL pointer dereference was fixed that could be
abused by a malicious USB device (bnc#1146519 1146524).
- CVE-2019-15220: A use-after-free issue was fixed that could be caused by
a malicious USB device (bnc#1146519 1146526).
- CVE-2019-15221: A NULL pointer dereference was fixed that could be
caused by a malicious USB device (bnc#1146519 1146529).
- CVE-2019-14814: A heap-based buffer overflow was fixed in the marvell
wifi chip driver. That issue allowed local users to cause a denial of
service (system crash) or possibly execute arbitrary code (bnc#1146512).
- CVE-2019-14815: A missing length check while parsing WMM IEs was fixed
(bsc#1146512, bsc#1146514, bsc#1146516).
- CVE-2019-14816: A heap-based buffer overflow in the marvell wifi chip
driver was fixed. Local users would have abused this issue to cause a
denial of service (system crash) or possibly execute arbitrary code
(bnc#1146516).
- CVE-2017-18509: An issue in net/ipv6 as fixed. By setting a specific
socket
option, an attacker could control a pointer in kernel land and cause an
inet_csk_listen_stop general protection fault, or potentially execute
arbitrary code under certain circumstances. The issue can be triggered
as root (e.g., inside a default LXC container or with the CAP_NET_ADMIN
capability) or after namespace unsharing. (bnc#1145477)
- CVE-2019-9506: The Bluetooth BR/EDR specification used to permit
sufficiently low encryption key length and did not prevent an attacker
from influencing the key length negotiation. This allowed practical
brute-force attacks (aka "KNOB") that could decrypt traffic and inject
arbitrary ciphertext without the victim noticing (bnc#1137865).
- CVE-2019-15098: A NULL pointer dereference in drivers/net/wireless/ath
was fixed (bnc#1146378).
