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

  - CVE-2014-9904
    It was discovered that the snd_compress_check_input
    function used in the ALSA subsystem does not properly
    check for an integer overflow, allowing a local user to
    cause a denial of service.

  - CVE-2016-5728
    Pengfei Wang discovered a race condition in the MIC VOP
    driver that could allow a local user to obtain sensitive
    information from kernel memory or cause a denial of
    service.

  - CVE-2016-5828
    Cyril Bur and Michael Ellerman discovered a flaw in the
    handling of Transactional Memory on powerpc systems
    allowing a local user to cause a denial of service
    (kernel crash) or possibly have unspecified other
    impact, by starting a transaction, suspending it, and
    then calling any of the exec() class system calls.

  - CVE-2016-5829
    A heap-based buffer overflow vulnerability was found in
    the hiddev driver, allowing a local user to cause a
    denial of service or, potentially escalate their
    privileges.

  - CVE-2016-6130
    Pengfei Wang discovered a flaw in the S/390 character
    device drivers potentially leading to information leak
    with /dev/sclp.

Additionally this update fixes a regression in the ebtables facility
(#828914) that was introduced in DSA-3607-1."

Red Hat Product Security has rated this update as having a security
impact of Important. A Common Vulnerability Scoring System (CVSS) base
score, which gives a detailed severity rating, is available for each
vulnerability from the CVE link(s) in the References section.

The kernel packages contain the Linux kernel, the core of any Linux
operating system.

Security Fix(es) :

* It was found that the Linux kernel's IPv6 implementation mishandled
socket options. A local attacker could abuse concurrent access to the
socket options to escalate their privileges, or cause a denial of
service (use-after-free and system crash) via a crafted sendmsg system
call. (CVE-2016-3841, Important)

* Several Moderate and Low impact security issues were found in the
Linux kernel. Space precludes documenting each of these issues in this
advisory. Refer to the CVE links in the References section for a
description of each of these vulnerabilities. (CVE-2013-4312,

CVE-2016-3857

Chiachih Wu reported two bugs in the ARM OABI compatibility layer that
can be used by local users for privilege escalation. The OABI
compatibility layer is enabled in all kernel flavours for armel and
armhf.

CVE-2016-4470

Wade Mealing of the Red Hat Product Security Team reported that in
some error cases the KEYS subsystem will dereference an uninitialised
pointer. A local user can use the keyctl() system call for denial of
service (crash) or possibly for privilege escalation.

CVE-2016-5696

Yue Cao, Zhiyun Qian, Zhongjie Wang, Tuan Dao, and Srikanth V.
Krishnamurthy of the University of California, Riverside; and Lisa M.
Marvel of the United States Army Research Laboratory discovered that
Linux's implementation of the TCP Challenge ACK feature results in a
side channel that can be used to find TCP connections between specific
IP addresses, and to inject messages into those connections.

Where a service is made available through TCP, this may
allow remote attackers to impersonate another connected user
to the server or to impersonate the server to another
connected user. In case the service uses a protocol with
message authentication (e.g. TLS or SSH), this vulnerability
only allows denial of service (connection failure). An
attack takes tens of seconds, so short-lived TCP connections
are also unlikely to be vulnerable.

This may be mitigated by increasing the rate limit for TCP
Challenge ACKs so that it is never exceeded: sysctl
net.ipv4.tcp_challenge_ack_limit=1000000000

CVE-2016-5829

Several heap-based buffer overflow vulnerabilities were found in the
hiddev driver, allowing a local user with access to a HID device to
cause a denial of service or potentially escalate their privileges.

CVE-2016-6136

Pengfei Wang discovered that the audit subsystem has a 'double-fetch'
or 'TOCTTOU' bug in its handling of special characters in the name of
an executable. Where audit logging of execve() is enabled, this allows
a local user to generate misleading log messages.

CVE-2016-6480

Pengfei Wang discovered that the aacraid driver for Adaptec RAID
controllers has a 'double-fetch' or 'TOCTTOU' bug in its validation of
'FIB' messages passed through the ioctl() system call. This has no
practical security impact in current Debian releases.

CVE-2016-6828

Marco Grassi reported a 'use-after-free' bug in the TCP
implementation, which can be triggered by local users. The security
impact is unclear, but might include denial of service or privilege
escalation.

CVE-2016-7118

Marcin Szewczyk reported that calling fcntl() on a file descriptor for
a directory on an aufs filesystem would result in am 'oops'. This
allows local users to cause a denial of service. This is a
Debian-specific regression introduced in version 3.2.81-1.

For Debian 7 'Wheezy', these problems have been fixed in version
3.2.81-2. This version also fixes a build failure (bug #827561) for
custom kernels with CONFIG_MODULES disabled, a regression in version
3.2.81-1. It also updates the PREEMPT_RT featureset to version
3.2.81-rt117.

For Debian 8 'Jessie', CVE-2016-3857 has no impact; CVE-2016-4470 and
CVE-2016-5829 were fixed in linux version 3.16.7-ckt25-2+deb8u3 or
earlier; and the remaining issues are fixed in version
3.16.36-1+deb8u1.

We recommend that you upgrade your linux packages.

"Security Fix(es) :

  - A flaw was found in the Linux kernel's keyring handling
    code, where in key_reject_and_link() an uninitialized
    variable would eventually lead to arbitrary free address
    which could allow attacker to use a use-after-free style
    attack. (CVE-2016-4470, Important)

  - A heap-based buffer overflow vulnerability was found in
    the Linux kernel's hiddev driver. This flaw could allow
    a local attacker to corrupt kernel memory, possible
    privilege escalation or crashing the system.
    (CVE-2016-5829, Moderate)

The CVE-2016-4470 issue was discovered by David Howells (Red Hat
Inc.).

Bug Fix(es) :

  - Previously, when two NFS shares with different security
    settings were mounted, the I/O operations to the
    kerberos-authenticated mount caused the
    RPC_CRED_KEY_EXPIRE_SOON parameter to be set, but the
    parameter was not unset when performing the I/O
    operations on the sec=sys mount. Consequently, writes to
    both NFS shares had the same parameters, regardless of
    their security settings. This update fixes this problem
    by moving the NO_CRKEY_TIMEOUT parameter to the
    auth->au_flags field. As a result, NFS shares with
    different security settings are now handled as expected.

  - In some circumstances, resetting a Fibre Channel over
    Ethernet (FCoE) interface could lead to a kernel panic,
    due to invalid information extracted from the FCoE
    header. This update adds santiy checking to the cpu
    number extracted from the FCoE header. This ensures that
    subsequent operations address a valid cpu, and
    eliminates the kernel panic.

  - Prior to this update, the following problems occurred
    with the way GSF2 transitioned files and directories
    from the 'unlinked' state to the 'free' state :

The numbers reported for the df and the du commands in some cases got
out of sync, which caused blocks in the file system to appear missing.
The blocks were not actually missing, but they were left in the
'unlinked' state.

In some circumstances, GFS2 referenced a cluster lock that was already
deleted, which led to a kernel panic.

If an object was deleted and its space reused as a different object,
GFS2 sometimes deleted the existing one, which caused file system
corruption.

With this update, the transition from 'unlinked' to 'free' state has
been fixed. As a result, none of these three problems occur anymore.

  - Previously, the GFS2 file system in some cases became
    unresponsive due to lock dependency problems between
    inodes and the cluster lock. This occurred most
    frequently on nearly full file systems where files and
    directories were being deleted and recreated at the same
    block location at the same time. With this update, a set
    of patches has been applied to fix these lock
    dependencies. As a result, GFS2 no longer hangs in the
    described circumstances.

  - When used with controllers that do not support DCMD-
    MR_DCMD_PD_LIST_QUERY, the megaraid_sas driver can go
    into infinite error reporting loop of error reporting
    messages. This could cause difficulties with finding
    other important log messages, or even it could cause the
    disk to overflow. This bug has been fixed by ignoring
    the DCMD MR_DCMD_PD_LIST_QUERY query for controllers
    which do not support it and sending the DCMD SUCCESS
    status to the AEN functions. As a result, the error
    messages no longer appear when there is a change in the
    status of one of the arrays."
