_____________________________________________________________________________

1. Problem Description

  When lynx calls external programs for protocols (e.g. telnet), the
  location is passed unchecked. This can be used to activate commandline
  parameters.
  For example, this reference  [A HREF="telnet://-n.rhosts"]click me[/A]
  would activate the tracefile options on the telnet client, with the
  result, that a .rhosts in the current directory would created or
  overwritten.

2. Impact

  Depending on the external programs called by lynx, files can be created
  or truncated, or even remote commands being executed if e.g. ssh or rsh
  would be configured in lynx.

3. Solution

  Updated the lynx package from our FTP server.
