tag_insight = "USN-1223-1 fixed vulnerabilities in Puppet. A regression was found on
  Ubuntu 10.04 LTS that caused permission denied errors when managing SSH
  authorized_keys files with Puppet. This update fixes the problem.

  We apologize for the inconvenience.
  
  Original advisory details:
  
  It was discovered that Puppet unsafely opened files when the k5login type
  is used to manage files. A local attacker could exploit this to overwrite
  arbitrary files which could be used to escalate privileges. (CVE-2011-3869)
  
  Ricky Zhou discovered that Puppet did not drop privileges when creating
  SSH authorized_keys files. A local attacker could exploit this to overwrite
  arbitrary files as root. (CVE-2011-3870)
  
  It was discovered that Puppet used a predictable filename when using the
  --edit resource. A local attacker could exploit this to edit arbitrary
  files or run arbitrary code as the user invoking the program, typically
  root. (CVE-2011-3871)";
