Vigilante Advisory #14 - HP Jetdirect print servers have multiple vulnerabilities which have effects ranging from the service crashing to the printer initiating a firmware upgrade based on random garbage in the memory, and in some cases powercycling won't fix the crash. It requires a new firmware burn by eg. HP to restore the Jetdirect card. The FTP, Telnet, and LPD services contain buffer overflows, and spoofed malformed packets can crash the printer. Fix available here.
