Package: bzflag-server
Severity: important
Tags: security

| The callsigns used by the clients are not checked or re-delimited by
| the server so is possible for a client to pass a callsign with no NULL
| bytes at its end causing problems (crash) to the server during the
| handling of this string.
| On both Linux and Windows for x86 (using the precompiled packages) I
| have reached the server crash without problems but is possible that in
| some configurations the crash could happen after many tries or also
| never, depending by how the memory is handled on that platform.
|
| The bug can be exploited also versus password protected servers without
| knowing the right keyword.

Please see http://aluigi.altervista.org/adv/bzflagboom-adv.txt for
details. It's been fixed upstream in 2.0.5.

Cheers,
