[continued from previous message]

A local user with access to a filesystem mounted with this option
could use this to cause a denial of service.

CVE-2018-1066

Dan Aloni reported to Red Hat that the CIFS client implementation
would dereference a null pointer if the server sent an invalid
response during NTLMSSP setup negotiation. This could be used
by a malicious server for denial of service.

CVE-2018-1068

The syzkaller tool found that the 32-bit compatibility layer of
ebtables did not sufficiently validate offset values. On a 64-bit
kernel, a local user with the CAP_NET_ADMIN capability (in any user
namespace) could use this to overwrite kernel memory, possibly
leading to privilege escalation. Debian disables unprivileged user
namespaces by default.

CVE-2018-1092

Wen Xu reported that a crafted ext4 filesystem image would
trigger a null dereference when mounted. A local user able
to mount arbitrary filesystems could use this for denial of
service.

CVE-2018-5332

Mohamed Ghannam reported that the RDS protocol did not
sufficiently validate RDMA requests, leading to an out-of-bounds
write. A local attacker on a system with the rds module loaded
could use this for denial of service or possibly for privilege
escalation.

CVE-2018-5333

Mohamed Ghannam reported that the RDS protocol did not properly
handle an error case, leading to a null pointer dereference. A
local attacker on a system with the rds module loaded could
possibly use this for denial of service.

CVE-2018-5750

Wang Qize reported that the ACPI sbshc driver logged a kernel heap
address. This information could aid the exploitation of other
vulnerabilities.

CVE-2018-5803

Alexey Kodanev reported that the SCTP protocol did not range-check
the length of chunks to be created. A local or remote user could
use this to cause a denial of service.

CVE-2018-6927

Li Jinyue reported that the FUTEX_REQUEUE operation on futexes did
not check for negative parameter values, which might lead to a
denial of service or other security impact.

CVE-2018-7492

The syzkaller tool found that the RDS protocol was lacking a null
pointer check. A local attacker on a system with the rds module
loaded could use this for denial of service.

CVE-2018-7566

Fan LongFei reported a race condition in the ALSA (sound)
sequencer core, between write and ioctl operations. This could
lead to an out-of-bounds access or use-after-free. A local user
with access to a sequencer device could use this for denial of
service or possibly for privilege escalation.

CVE-2018-7740

Nic Losby reported that the hugetlbfs filesystem's mmap operation
did not properly range-check the file offset. A local user with
access to files on a hugetlbfs filesystem could use this to cause
a denial of service.

CVE-2018-7757

Jason Yan reported a memory leak in the SAS (Serial-Attached
SCSI) subsystem. A local user on a system with SAS devices
could use this to cause a denial of service.

CVE-2018-7995

Seunghun Han reported a race condition in the x86 MCE
(Machine Check Exception) driver. This is unlikely to have
any security impact.

CVE-2018-8781

Eyal Itkin reported that the udl (DisplayLink) driver's mmap
operation did not properly range-check the file offset. A local
user with access to a udl framebuffer device could exploit this to
overwrite kernel memory, leading to privilege escalation.

CVE-2018-8822

Dr Silvio Cesare of InfoSect reported that the ncpfs client
implementation did not validate reply lengths from the server. An
ncpfs server could use this to cause a denial of service or
remote code execution in the client.

CVE-2018-1000004

Luo Quan reported a race condition in the ALSA (sound) sequencer
core, between multiple ioctl operations. This could lead to a
deadlock or use-after-free. A local user with access to a
sequencer device could use this for denial of service or possibly
for privilege escalation.

CVE-2018-1000199

Andy Lutomirski discovered that the ptrace subsystem did not
sufficiently validate hardware breakpoint settings. Local users
can use this to cause a denial of service, or possibly for
privilege escalation, on x86 (amd64 and i386) and possibly other
architectures.

For the oldstable distribution (jessie), these problems have been fixed
in version 3.16.56-1.

We recommend that you upgrade your linux packages.
