Several vulnerabilities have been discovered in the Linux kernel that
may lead to a privilege escalation, denial of service or information
leaks.

CVE-2018-6554

A memory leak in the irda_bind function in the irda subsystem was
discovered. A local user can take advantage of this flaw to cause a
denial of service (memory consumption).

CVE-2018-6555

A flaw was discovered in the irda_setsockopt function in the irda
subsystem, allowing a local user to cause a denial of service
(use-after-free and system crash).

CVE-2018-7755

Brian Belleville discovered a flaw in the fd_locked_ioctl function
in the floppy driver in the Linux kernel. The floppy driver copies a
kernel pointer to user memory in response to the FDGETPRM ioctl. A
local user with access to a floppy drive device can take advantage
of this flaw to discover the location kernel code and data.

CVE-2018-9363

It was discovered that the Bluetooth HIDP implementation did not
correctly check the length of received report messages. A paired
HIDP device could use this to cause a buffer overflow, leading to
denial of service (memory corruption or crash) or potentially
remote code execution.

CVE-2018-9516

It was discovered that the HID events interface in debugfs did not
correctly limit the length of copies to user buffers. A local
user with access to these files could use this to cause a
denial of service (memory corruption or crash) or possibly for
privilege escalation. However, by default debugfs is only
accessible by the root user.

CVE-2018-10902

It was discovered that the rawmidi kernel driver does not protect
against concurrent access which leads to a double-realloc (double
free) flaw. A local attacker can take advantage of this issue for
privilege escalation.

CVE-2018-10938

Yves Younan from Cisco reported that the Cipso IPv4 module did not
correctly check the length of IPv4 options. On custom kernels with
CONFIG_NETLABEL enabled, a remote attacker could use this to cause
a denial of service (hang).

CVE-2018-13099

Wen Xu from SSLab at Gatech reported a use-after-free bug in the
F2FS implementation. An attacker able to mount a crafted F2FS
volume could use this to cause a denial of service (crash or
memory corruption) or possibly for privilege escalation.

CVE-2018-14609

Wen Xu from SSLab at Gatech reported a potential null pointer
dereference in the F2FS implementation. An attacker able to mount
a crafted F2FS volume could use this to cause a denial of service
(crash).

CVE-2018-14617

Wen Xu from SSLab at Gatech reported a potential null pointer
dereference in the HFS+ implementation. An attacker able to mount
a crafted HFS+ volume could use this to cause a denial of service
(crash).

CVE-2018-14633

Vincent Pelletier discovered a stack-based buffer overflow flaw in
the chap_server_compute_md5() function in the iSCSI target code. An
unauthenticated remote attacker can take advantage of this flaw to
cause a denial of service or possibly to get a non-authorized access
to data exported by an iSCSI target.

CVE-2018-14678

M. Vefa Bicakci and Andy Lutomirski discovered a flaw in the
kernel exit code used on amd64 systems running as Xen PV guests.
A local user could use this to cause a denial of service (crash).

CVE-2018-14734

A use-after-free bug was discovered in the InfiniBand
communication manager. A local user could use this to cause a
denial of service (crash or memory corruption) or possible for
privilege escalation.

CVE-2018-15572

Esmaiel Mohammadian Koruyeh, Khaled Khasawneh, Chengyu Song, and
Nael Abu-Ghazaleh, from University of California, Riverside,
reported a variant of Spectre variant 2, dubbed SpectreRSB. A
local user may be able to use this to read sensitive information
from processes owned by other users.

CVE-2018-15594

Nadav Amit reported that some indirect function calls used in
paravirtualised guests were vulnerable to Spectre variant 2. A
local user may be able to use this to read sensitive information
from the kernel.

CVE-2018-16276

Jann Horn discovered that the yurex driver did not correctly limit
the length of copies to user buffers. A local user with access to
a yurex device node could use this to cause a denial of service
(memory corruption or crash) or possibly for privilege escalation.

CVE-2018-16658

It was discovered that the cdrom driver does not correctly
validate the parameter to the CDROM_DRIVE_STATUS ioctl. A user
with access to a cdrom device could use this to read sensitive
information from the kernel or to cause a denial of service
(crash).

CVE-2018-17182

Jann Horn discovered that the vmacache_flush_all function mishandles
sequence number overflows. A local user can take advantage of this
flaw to trigger a use-after-free, causing a denial of service
(crash or memory corruption) or privilege escalation.

For the stable distribution (stretch), these problems have been fixed in
version 4.9.110-3+deb9u5.

We recommend that you upgrade your linux packages.
