The remote host is missing an update to jazip announced via advisory DSA 017-1.
With older versions of jazip a user could gain root access for members of the floppy group to the local machine. The interface doesn't run as root anymore and this very exploit was prevented. The program now also truncates DISPLAY to 256 characters if it is bigger, which closes the buffer overflow (within xforms). We recommend you upgrade your jazip package immediately.
