           Summary: Telnet option handlers subnegotiations does not handle
                    0xFF correctly
           Product: Commons
           Version: unspecified
          Platform: Other
        OS/Version: other
            Status: NEW
          Severity: minor
          Priority: P2
         Component: Net
        AssignedTo: commons-dev@jakarta.apache.org
        ReportedBy: yuvalkashtan@gmail.com


in accordance to RFC855: "Finally, if parameters in an option "subnegotiation"
include a byte with a value of 255, it is necessary to double this byte in
accordance the general TELNET rules."

I've actually encontered this while implementing WindowSize option handler, but
it seems that all the currently avilable handlers are vulnerable to this.
