linux - security update

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.

For the stable distribution (jessie), these problems have been fixed in
version 3.16.7-ckt25-2+deb8u3.

We recommend that you upgrade your linux packages.
