tag_insight = "It was discovered that the security fix for CVE-2010-4250 introduced a
  regression. A remote attacker could exploit this to crash the system,
  leading to a denial of service. (CVE-2011-1479)

  Vasiliy Kulikov discovered that taskstats did not enforce access
  restrictions. A local attacker could exploit this to read certain
  information, leading to a loss of privacy. (CVE-2011-2494)
  
  Vasiliy Kulikov discovered that /proc/PID/io did not enforce access
  restrictions. A local attacker could exploit this to read certain
  information, leading to a loss of privacy. (CVE-2011-2495)
  
  It was discovered that the EXT4 filesystem contained multiple off-by-one
  flaws. A local attacker could exploit this to crash the system, leading to
  a denial of service. (CVE-2011-2695)
  
  Christian Ohm discovered that the perf command looks for configuration
  files in the current directory. If a privileged user were tricked into
  running perf in a directory containing a malicious configuration file, an
  attacker could run arbitrary commands and possibly gain privileges.
  (CVE-2011-2905)
  
  Vasiliy Kulikov discovered that the Comedi driver did not correctly clear
  memory. A local attacker could exploit this to read kernel stack memory,
  leading to a loss of privacy. (CVE-2011-2909)
  
  Dan Kaminsky discovered that the kernel incorrectly handled random sequence
  number generation. An attacker could use this flaw to possibly predict
  sequence numbers and inject packets. (CVE-2011-3188)
  
  Yogesh Sharma discovered that CIFS did not correctly handle UNCs that had
  no prefixpaths. A local attacker with access to a CIFS partition could
  exploit this to crash the system, leading to a denial of service.
