tag_insight = "It was discovered that the /proc filesystem did not correctly handle
  permission changes when programs executed. A local attacker could hold open
  files to examine details about programs running with higher privileges,
  potentially increasing the chances of exploiting additional
  vulnerabilities. (CVE-2011-1020)

  Dan Rosenberg discovered that the X.25 Rose network stack did not correctly
  handle certain fields. If a system was running with Rose enabled, a remote
  attacker could send specially crafted traffic to gain root privileges.
  (CVE-2011-1493)
  
  Vasiliy Kulikov and Dan Rosenberg discovered that ecryptfs did not
  correctly check the origin of mount points. A local attacker could exploit
  this to trick the system into unmounting arbitrary mount points, leading to
  a denial of service. (CVE-2011-1833)
  
  It was discovered that Bluetooth l2cap and rfcomm did not correctly
  initialize structures. A local attacker could exploit this to read portions
  of the kernel stack, leading to a loss of privacy. (CVE-2011-2492)
  
  It was discovered that GFS2 did not correctly check block sizes. A local
  attacker could exploit this to crash the system, leading to a denial of
  service. (CVE-2011-2689)
  
  Fernando Gont discovered that the IPv6 stack used predictable fragment
  identification numbers. A remote attacker could exploit this to exhaust
  network resources, leading to a denial of service. (CVE-2011-2699)
  
  The performance counter subsystem did not correctly handle certain
  counters. A local attacker could exploit this to crash the system, leading
  to a denial of service. (CVE-2011-2918)";
