Vulnerability Description
A denial of service vulnerability has been reported in Hewlett-Packard (HP) Printers with HP FTP Print Server. The vulnerability could be exploited by remote attackers to crash the application via a specially crafted FTP command sent to an affected server.
Vulnerability Details
