Sebb updated NET-74:

    Component/s: Telnet

> [net]Telnet option handlers subnegotiations does not handle 0xFF correctly
> --------------------------------------------------------------------------

>                 Key: NET-74
>                 URL: https://issues.apache.org/jira/browse/NET-74
>             Project: Commons Net
>          Issue Type: Bug
>          Components: Telnet
>         Environment: Operating System: other

> 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.
