tag_insight = "A denial of service condition was found in Ruby's regular expression
  engine.  If a Ruby script tried to process a large amount of data
  via a regular expression, it could cause Ruby to enter an infinite
  loop and crash (CVE-2008-3443).

  A number of flaws were found in Ruby that could allow an attacker to
  create a carefully crafted script that could allow for the bypass of
  certain safe-level restrictions (CVE-2008-3655).
  
  A denial of service vulnerability was found in Ruby's HTTP server
  toolkit, WEBrick.  A remote attacker could send a specially-crafted
  HTTP request to a WEBrick server that would cause it to use an
  excessive amount of CPU time (CVE-2008-3656).
  
  An insufficient taintness check issue was found in Ruby's DL module,
  a module that provides direct access to the C language functions.
  This flaw could be used by an attacker to bypass intended safe-level
  restrictions by calling external C functions with the arguments from
  an untrusted tainted input (CVE-2008-3657).
  
  A denial of service condition in Ruby's XML document parsing module
  (REXML) could cause a Ruby application using the REXML module to use
  an excessive amount of CPU and memory via XML documents with large
  XML entity definitions recursion (CVE-2008-3790).
  
  The Ruby DNS resolver library used predictable transaction IDs and
  a fixed source port when sending DNS requests.  This could be used
  by a remote attacker to spoof a malicious reply to a DNS query
  (CVE-2008-3905).
  
  The updated packages have been patched to correct these issues.";
