"The remote NewStart CGSL host, running version MAIN 4.05, has kernel packages installed that are affected by multiple
vulnerabilities:

  - It was found that the fix for CVE-2016-9576 was
    incomplete: the Linux kernel's sg implementation did not
    properly restrict write operations in situations where
    the KERNEL_DS option is set. A local attacker to read or
    write to arbitrary kernel memory locations or cause a
    denial of service (use-after-free) by leveraging write
    access to a /dev/sg device. (CVE-2016-10088)

  - When creating audit records for parameters to executed
    children processes, an attacker can convince the Linux
    kernel audit subsystem can create corrupt records which
    may allow an attacker to misrepresent or evade logging
    of executing commands. (CVE-2016-6136)

  - A flaw was found in the Linux kernel's implementation of
    seq_file where a local attacker could manipulate memory
    in the put() function pointer. This could lead to memory
    corruption and possible privileged escalation.
    (CVE-2016-7910)

  - It was found that the blk_rq_map_user_iov() function in
    the Linux kernel's block device implementation did not
    properly restrict the type of iterator, which could
    allow a local attacker to read or write to arbitrary
    kernel memory locations or cause a denial of service
    (use-after-free) by leveraging write access to a /dev/sg
    device. (CVE-2016-9576)

  - A stack buffer overflow flaw was found in the way the
    Bluetooth subsystem of the Linux kernel processed
    pending L2CAP configuration responses from a client. On
    systems with the stack protection feature enabled in the
    kernel (CONFIG_CC_STACKPROTECTOR=y, which is enabled on
    all architectures other than s390x and ppc64[le]), an
    unauthenticated attacker able to initiate a connection
    to a system via Bluetooth could use this flaw to crash
    the system. Due to the nature of the stack protection
    feature, code execution cannot be fully ruled out,
    although we believe it is unlikely. On systems without
    the stack protection feature (ppc64[le]; the Bluetooth
    modules are not built on s390x), an unauthenticated
    attacker able to initiate a connection to a system via
    Bluetooth could use this flaw to remotely execute
    arbitrary code on the system with ring 0 (kernel)
    privileges. (CVE-2017-1000251)

  - A flaw was found in the way the Linux kernel loaded ELF
    executables. Provided that an application was built as
    Position Independent Executable (PIE), the loader could
    allow part of that application's data segment to map
    over the memory area reserved for its stack, potentially
    resulting in memory corruption. An unprivileged local
    user with access to SUID (or otherwise privileged) PIE
    binary could use this flaw to escalate their privileges
    on the system. (CVE-2017-1000253)

  - A use-after-free flaw was found in the way the Linux
    kernel's Datagram Congestion Control Protocol (DCCP)
    implementation freed SKB (socket buffer) resources for a
    DCCP_PKT_REQUEST packet when the IPV6_RECVPKTINFO option
    is set on the socket. A local, unprivileged user could
    use this flaw to alter the kernel memory, allowing them
    to escalate their privileges on the system.

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

CVE-2012-6704, CVE-2016-9793

Eric Dumazet found that a local user with CAP_NET_ADMIN capability
could set a socket's buffer size to be negative, leading to a denial
of service or other security impact. Additionally, in kernel versions
prior to 3.5, any user could do this if sysctl net.core.rmem_max was
changed to a very large value.

CVE-2015-1350 / #770492

Ben Harris reported that local users could remove set-capability
attributes from any file visible to them, allowing a denial of
service.

CVE-2015-8962

Calvin Owens fouund that removing a SCSI device while it was being
accessed through the SCSI generic (sg) driver led to a double- free,
possibly causing a denial of service (crash or memory corruption) or
privilege escalation. This could be exploited by local users with
permision to access a SCSI device node.

CVE-2015-8963

Sasha Levin reported that hot-unplugging a CPU resulted in a
use-after-free by the performance events (perf) subsystem, possibly
causing a denial of service (crash or memory corruption) or privilege
escalation. This could by exploited by any local user.

CVE-2015-8964

It was found that the terminal/serial (tty) subsystem did not reliably
reset the terminal buffer state when the terminal line discipline was
changed. This could allow a local user with access to a terminal
device to read sensitive information from kernel memory.

CVE-2016-7097

Jan Kara found that changing the POSIX ACL of a file never cleared its
set-group-ID flag, which should be done if the user changing it is not
a member of the group-owner. In some cases, this would allow the
user-owner of an executable to gain the privileges of the group-owner.

CVE-2016-7910

Vegard Nossum discovered that a memory allocation failure while
handling a read of /proc/diskstats or /proc/partitions could lead to a
use-after-free, possibly causing a denial of service (crash or memory
corruption) or privilege escalation.

CVE-2016-7911

Dmitry Vyukov reported that a race between ioprio_get() and
ioprio_set() system calls could result in a use-after-free, possibly
causing a denial of service (crash) or leaking sensitive information.

CVE-2016-7915

Benjamin Tissoires found that HID devices could trigger an out-of-
bounds memory access in the HID core. A physically present user could
possibly use this for denial of service (crash) or to leak sensitive
information.

CVE-2016-8399

Qidan He reported that the IPv4 ping socket implementation did not
validate the length of packets to be sent. A user with permisson to
use ping sockets could cause an out-of-bounds read, possibly resulting
in a denial of service or information leak. However, on Debian systems
no users have permission to create ping sockets by default.

CVE-2016-8633

Eyal Itkin reported that the IP-over-Firewire driver (firewire-net)
did not validate the offset or length in link-layer fragmentation
headers. This allowed a remote system connected by Firewire to write
to memory after a packet buffer, leading to a denial of service
(crash) or remote code execution.

CVE-2016-8645

Marco Grassi reported that if a socket filter (BPF program) attached
to a TCP socket truncates or removes the TCP header, this could cause
a denial of service (crash). This was exploitable by any local user.

CVE-2016-8655

Philip Pettersson found that the implementation of packet sockets
(AF_PACKET family) had a race condition between enabling a transmit
ring buffer and changing the version of buffers used, which could
result in a use-after-free. A local user with the CAP_NET_ADMIN
capability could exploit this for privilege escalation.

CVE-2016-9178

Al Viro found that a failure to read data from user memory might lead
to a information leak on the x86 architecture (amd64 or i386).

CVE-2016-9555

Andrey Konovalov reported that the SCTP implementation does not
validate 'out of the blue' packet chunk lengths early enough. A remote
system able could use this to cause a denial of service (crash) or
other security impact for systems using SCTP.

CVE-2016-9576, CVE-2016-10088

Dmitry Vyukov reported that using splice() with the SCSI generic
driver led to kernel memory corruption. Local users with permision to
access a SCSI device node could exploit this for privilege escalation.

CVE-2016-9756

Dmitry Vyukov reported that KVM for the x86 architecture (amd64 or
i386) did not correctly handle the failure of certain instructions
that require software emulation on older processors. This could be
exploited by guest systems to leak sensitive information or for denial
of service (log spam).

CVE-2016-9794

Baozeng Ding reported a race condition in the ALSA (sound) subsystem
that could result in a use-after-free. Local users with access to a
PCM sound device could exploit this for denial of service (crash or
memory corruption) or other security impact.

For Debian 7 'Wheezy', these problems have been fixed in version
3.2.84-1. This version also includes bug fixes from upstream version
3.2.84 and updates the PREEMPT_RT featureset to version 3.2.84-rt122.
Finally, this version adds the option to mitigate security issues in
the performance events (perf) subsystem by disabling use by
unprivileged users. This can be done by setting sysctl
kernel.perf_event_paranoid=3.

For Debian 8 'Jessie', these problems have been fixed in version
3.16.39-1 which will be included in the next point release (8.6).

"An update for kernel is now available for Red Hat Enterprise Linux 7.

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 packet_set_ring() function of the Linux
kernel's networking implementation did not properly validate certain
block-size data. A local attacker with CAP_NET_RAW capability could
use this flaw to trigger a buffer overflow, resulting in the crash of
the system. Due to the nature of the flaw, privilege escalation cannot
be fully ruled out. (CVE-2017-7308, Important)

* Mounting a crafted EXT4 image read-only leads to an attacker
controlled memory corruption and SLAB-Out-of-Bounds reads.
(CVE-2016-10208, Moderate)

* A flaw was found in the Linux kernel's implementation of seq_file
where a local attacker could manipulate memory in the put() function
pointer. This could lead to memory corruption and possible privileged
escalation. (CVE-2016-7910, Moderate)

* A vulnerability was found in the Linux kernel. An unprivileged local
user could trigger oops in shash_async_export() by attempting to force
the in-kernel hashing algorithms into decrypting an empty data set.
(CVE-2016-8646, Moderate)

* It was reported that with Linux kernel, earlier than version
v4.10-rc8, an application may trigger a BUG_ON in sctp_wait_for_sndbuf
if the socket tx buffer is full, a thread is waiting on it to queue
more data, and meanwhile another thread peels off the association
being used by the first thread. (CVE-2017-5986, Moderate)

Red Hat would like to thank Igor Redko (Virtuozzo kernel team) for
reporting CVE-2016-8646.

"An update for kernel is now available for Red Hat Enterprise Linux 6.

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) :

* A race condition flaw was found in the N_HLDC Linux kernel driver
when accessing n_hdlc.tbuf list that can lead to double free. A local,
unprivileged user able to set the HDLC line discipline on the tty
device could use this flaw to increase their privileges on the system.
(CVE-2017-2636, Important)

* A flaw was found in the Linux kernel's implementation of seq_file
where a local attacker could manipulate memory in the put() function
pointer. This could lead to memory corruption and possible privileged
escalation. (CVE-2016-7910, Moderate)

Red Hat would like to thank Alexander Popov for reporting
CVE-2017-2636.

Bug Fix(es) :

* Previously, Chelsio firmware included an incorrectly-formatted
firmware bin file. As a consequence, the firmware could not be
flashed. This update provides a firmware bin file that is formatted
correctly. As a result, Chelsio firmware can now be flashed
successfully. (BZ#1433865)

* When multiple simultaneous processes attempted to read from the
/proc/stat file, spinlock overhead was generated on Non-Uniform Memory
Access (NUMA) systems. Consequently, a large amount of CPU was
consumed. With this update, the underlying source code has been fixed
to avoid taking spinlock when the interrupt line does not exist. As a
result, the spinlock overhead is now generated less often, and
multiple simultaneous processes can now read /proc/stat without
consuming a large amount of CPU. (BZ#1428106)
