  Remote Help is prone to a denial-of-service vulnerability.
  
  Remote attackers can exploit this issue to cause the application to crash, denying service to legitimate users. Due to the nature of this issue arbitrary code-execution may be possible; however this has not been confirmed.
  
  Remote Help 0.0.7 is vulnerable; other versions may also be affected.
