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-2015-8956
  It was discovered that missing input sanitising in RFCOMM Bluetooth
  socket handling may result in denial of service or information leak.
• CVE-2016-5195
  It was discovered that a race condition in the memory management
  code can be used for local privilege escalation.
• CVE-2016-7042
  Ondrej Kozina discovered that incorrect buffer allocation in the
  proc_keys_show() function may result in local denial of service.
• CVE-2016-7425
  Marco Grassi discovered a buffer overflow in the arcmsr SCSI driver
  which may result in local denial of service, or potentially,
  arbitrary code execution.

Additionally this update fixes a regression introduced in DSA-3616-1
causing iptables performance issues (cf. Debian Bug #831014).

For the stable distribution (jessie), these problems have been fixed in
version 3.16.36-1+deb8u2.

We recommend that you upgrade your linux packages.
