tag_insight = "rdesktop is an open source client for Microsoft Windows NT Terminal Server
  and Microsoft Windows 2000 and 2003 Terminal Services, capable of natively
  using the Remote Desktop Protocol (RDP) to present the user's NT desktop.
  No additional server extensions are required.

  An integer underflow vulnerability was discovered in the rdesktop. If an
  attacker could convince a victim to connect to a malicious RDP server, the
  attacker could cause the victim's rdesktop to crash or, possibly, execute
  an arbitrary code. (CVE-2008-1801)
  
  Additionally, the following bug was fixed:
  
  A missing command line option caused rdesktop to fail when using the krdc
  remote desktop utility. Using krdc to connect to a terminal server resulted
  in errors such as the following:
  
  The version of rdesktop you are using ([version]) is too old:
  
  rdesktop [version] or greater is required. A working patch for rdesktop
  [version] can be found in KDE CVS.
  
  In this updated package, krdc successfully connects to terminal servers.
  
  Users of rdesktop should upgrade to these updated packages, which contain a
  backported patches to resolve these issues.";
