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

CVE-2016-10905

A race condition was discovered in the GFS2 file-system
implementation, which could lead to a use-after-free. On a system
using GFS2, a local attacker could use this for denial of service
(memory corruption or crash) or possibly for privilege escalation.

CVE-2018-20976

It was discovered that the XFS file-system implementation did not
correctly handle some mount failure conditions, which could lead
to a use-after-free. The security impact of this is unclear.

CVE-2018-21008

It was discovered that the rsi wifi driver did not correctly
handle some failure conditions, which could lead to a use-after-
free. The security impact of this is unclear.

CVE-2019-0136

It was discovered that the wifi soft-MAC implementation (mac80211)
did not properly authenticate Tunneled Direct Link Setup (TDLS)
messages. A nearby attacker could use this for denial of service
(loss of wifi connectivity).

CVE-2019-9506

Daniele Antonioli, Nils Ole Tippenhauer, and Kasper Rasmussen
discovered a weakness in the Bluetooth pairing protocols, dubbed
the "KNOB attack". An attacker that is nearby during pairing
could use this to weaken the encryption used between the paired
devices, and then to eavesdrop on and/or spoof communication
between them.

This update mitigates the attack by requiring a minimum encryption
key length of 56 bits.

CVE-2019-14814, CVE-2019-14815, CVE-2019-14816

Multiple bugs were discovered in the mwifiex wifi driver, which
could lead to heap buffer overflows. A local user permitted to
configure a device handled by this driver could probably use this
for privilege escalation.

CVE-2019-14821

Matt Delco reported a race condition in KVM's coalesced MMIO
facility, which could lead to out-of-bounds access in the kernel.
A local attacker permitted to access /dev/kvm could use this to
cause a denial of service (memory corruption or crash) or possibly
for privilege escalation.

CVE-2019-14835

Peter Pi of Tencent Blade Team discovered a missing bounds check
in vhost_net, the network back-end driver for KVM hosts, leading
to a buffer overflow when the host begins live migration of a VM.
An attacker in control of a VM could use this to cause a denial of
service (memory corruption or crash) or possibly for privilege
escalation on the host.

CVE-2019-15117

Hui Peng and Mathias Payer reported a missing bounds check in the
usb-audio driver's descriptor parsing code, leading to a buffer
over-read. An attacker able to add USB devices could possibly use
this to cause a denial of service (crash).

CVE-2019-15118

Hui Peng and Mathias Payer reported unbounded recursion in the
usb-audio driver's descriptor parsing code, leading to a stack
overflow. An attacker able to add USB devices could use this to
cause a denial of service (memory corruption or crash) or possibly
for privilege escalation.

CVE-2019-15211

The syzkaller tool found a bug in the radio-raremono driver that
could lead to a use-after-free. An attacker able to add and
remove USB devices could use this to cause a denial of service
(memory corruption or crash) or possibly for privilege escalation.

CVE-2019-15212

The syzkaller tool found that the rio500 driver does not work
correctly if more than one device is bound to it. An attacker
able to add USB devices could use this to cause a denial of
service (memory corruption or crash) or possibly for privilege
escalation.

CVE-2019-15215

The syzkaller tool found a bug in the cpia2_usb driver that leads
to a use-after-free. An attacker able to add and remove USB
devices could use this to cause a denial of service (memory
corruption or crash) or possibly for privilege escalation.

CVE-2019-15218

The syzkaller tool found that the smsusb driver did not validate
that USB devices have the expected endpoints, potentially leading
to a null pointer dereference. An attacker able to add USB
devices could use this to cause a denial of service (BUG/oops).

CVE-2019-15219

The syzkaller tool found that a device initialisation error in the
sisusbvga driver could lead to a null pointer dereference. An
attacker able to add USB devices could use this to cause a denial
of service (BUG/oops).

CVE-2019-15220

The syzkaller tool found a race condition in the p54usb driver
which could lead to a use-after-free. An attacker able to add and
remove USB devices could use this to cause a denial of service
(memory corruption or crash) or possibly for privilege escalation.

CVE-2019-15221

The syzkaller tool found that the line6 driver did not validate
USB devices' maximum packet sizes, which could lead to a heap
buffer overrun. An attacker able to add USB devices could use
this to cause a denial of service (memory corruption or crash) or
possibly for privilege escalation.

CVE-2019-15292

The Hulk Robot tool found missing error checks in the Appletalk
protocol implementation, which could lead to a use-after-free.
The security impact of this is unclear.

CVE-2019-15807

Jian Luo reported that the Serial Attached SCSI library (libsas)
did not correctly handle failure to discover devices beyond a SAS
expander. This could lead to a resource leak and crash (BUG).
The security impact of this is unclear.

CVE-2019-15917

The syzkaller tool found a race condition in code supporting
UART-attached Bluetooth adapters, which could lead to a use-
after-free. A local user with access to a pty device or other
suitable tty device could use this to cause a denial of service
(memory corruption or crash) or possibly for privilege escalation.

CVE-2019-15926

It was found that the ath6kl wifi driver did not consistently
validate traffic class numbers in received control packets,
leading to out-of-bounds memory accesses. A nearby attacker on
the same wifi network could use this to cause a denial of service
(memory corruption or crash) or possibly for privilege escalation.

For Debian 8 "Jessie", these problems have been fixed in version
3.16.74-1.

We recommend that you upgrade your linux packages.

allow unauthenticated users to modify published content and write to
the database, perform cross-site request forgeries, and enumerate
registered users.

For the oldstable distribution (stretch), these problems have been fixed
in version 3.1.4-4~deb9u3.

For the stable distribution (buster), these problems have been fixed in
version 3.2.4-1+deb10u1.
