Ubuntu Security Notice USN-2967-1
May 09, 2016

linux vulnerabilities
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 12.04 LTS

Summary:

Several security issues were fixed in the kernel.

Software Description:
- linux: Linux kernel

Details:

It was discovered that the Linux kernel did not properly enforce rlimits
for file descriptors sent over UNIX domain sockets. A local attacker could
use this to cause a denial of service. (CVE-2013-4312)

Ralf Spenneberg discovered that the Aiptek Tablet USB device driver in the
Linux kernel did not properly sanity check the endpoints reported by the
device. An attacker with physical access could cause a denial of service
(system crash). (CVE-2015-7515)

Ralf Spenneberg discovered that the USB driver for Clie devices in the
Linux kernel did not properly sanity check the endpoints reported by the
device. An attacker with physical access could cause a denial of service
(system crash). (CVE-2015-7566)

Ralf Spenneberg discovered that the usbvision driver in the Linux kernel
did not properly sanity check the interfaces and endpoints reported by the
device. An attacker with physical access could cause a denial of service
(system crash). (CVE-2015-7833)

It was discovered that a race condition existed when handling heartbeat-
timeout events in the SCTP implementation of the Linux kernel. A remote
attacker could use this to cause a denial of service. (CVE-2015-8767)

Venkatesh Pottem discovered a use-after-free vulnerability in the Linux
kernel's CXGB3 driver. A local attacker could use this to cause a denial of
service (system crash) or possibly execute arbitrary code. (CVE-2015-8812)

It was discovered that a race condition existed in the ioctl handler for
the TTY driver in the Linux kernel. A local attacker could use this to
cause a denial of service (system crash) or expose sensitive information.
(CVE-2016-0723)

It was discovered that the Linux kernel did not keep accurate track of pipe
buffer details when error conditions occurred, due to an incomplete fix for
CVE-2015-1805. A local attacker could use this to cause a denial of service
(system crash) or possibly execute arbitrary code with administrative
privileges. (CVE-2016-0774)

Zach Riggle discovered that the Linux kernel's list poison feature did not
take into account the mmap_min_addr value. A local attacker could use this
to bypass the kernel's poison-pointer protection mechanism while attempting
to exploit an existing kernel vulnerability. (CVE-2016-0821)

Andy Lutomirski discovered a race condition in the Linux kernel's
translation lookaside buffer (TLB) handling of flush events. A local
attacker could use this to cause a denial of service or possibly leak
sensitive information. (CVE-2016-2069)

Dmitry Vyukov discovered that the Advanced Linux Sound Architecture (ALSA)
framework did not verify that a FIFO was attached to a client before
attempting to clear it. A local attacker could use this to cause a denial
of service (system crash). (CVE-2016-2543)

Dmitry Vyukov discovered that a race condition existed in the Advanced
Linux Sound Architecture (ALSA) framework between timer setup and closing
of the client, resulting in a use-after-free. A local attacker could use
this to cause a denial of service. (CVE-2016-2544)

Dmitry Vyukov discovered a race condition in the timer handling
implementation of the Advanced Linux Sound Architecture (ALSA) framework,
resulting in a use-after-free. A local attacker could use this to cause a
denial of service (system crash). (CVE-2016-2545)

Dmitry Vyukov discovered race conditions in the Advanced Linux Sound
Architecture (ALSA) framework's timer ioctls leading to a use-after-free. A
local attacker could use this to cause a denial of service (system crash)
or possibly execute arbitrary code. (CVE-2016-2546)

Dmitry Vyukov discovered that the Advanced Linux Sound Architecture (ALSA)
framework's handling of high resolution timers did not properly manage its
data structures. A local attacker could use this to cause a denial of
service (system hang or crash) or possibly execute arbitrary code.
(CVE-2016-2547, CVE-2016-2548)

Dmitry Vyukov discovered that the Advanced Linux Sound Architecture (ALSA)
framework's handling of high resolution timers could lead to a deadlock
condition. A local attacker could use this to cause a denial of service
(system hang). (CVE-2016-2549)

Ralf Spenneberg discovered that the USB driver for Treo devices in the
Linux kernel did not properly sanity check the endpoints reported by the
device. An attacker with physical access could cause a denial of service
(system crash). (CVE-2016-2782)

It was discovered that the Linux kernel did not enforce limits on the
amount of data allocated to buffer pipes. A local attacker could use this
to cause a denial of service (resource exhaustion). (CVE-2016-2847)

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 12.04 LTS:
linux-image-3.2.0-102-generic 3.2.0-102.142
linux-image-3.2.0-102-generic-pae 3.2.0-102.142
linux-image-3.2.0-102-highbank 3.2.0-102.142
linux-image-3.2.0-102-omap 3.2.0-102.142
linux-image-3.2.0-102-powerpc-smp 3.2.0-102.142
linux-image-3.2.0-102-powerpc64-smp 3.2.0-102.142
linux-image-3.2.0-102-virtual 3.2.0-102.142

After a standard system update you need to reboot your computer to make
all the necessary changes.

ATTENTION: Due to an unavoidable ABI change the kernel updates have
been given a new version number, which requires you to recompile and
reinstall all third party kernel modules you might have installed.
Unless you manually uninstalled the standard kernel metapackages
(e.g. linux-generic, linux-generic-lts-RELEASE, linux-virtual,
linux-powerpc), a standard system upgrade will automatically perform
this as well.
