Bugzilla Bug 162092

Vulnerable Systems:
 * Marathon Aleph One versions released before 16 Dec 2006

Empty connection crash:
It's possible to cause the crash of the server simply doing an empty connection
to it followed by a valid one (or vice versa, the cause of this bug is not
clear and not investigated yet).

Possible format string in the logging function:
logMessageV, the function used for logging anything in the game, is vulnerable
to a format string bug. The logging is enabled ONLY with log messages having a
priority level minor than logNoteLevel (40) like logFatalLevel, logErrorLevel,
logWarningLevel and logAnomalyLevel. Luigi has tried to search an easy way for
exploiting this bug from remote but without luck so Luigi doesn't know if exist
or what are the other ways (both remote and local) for doing it.

Reproducible: Didn't try

Okay, will do.  I wasn't quite sure how far I was supposed to take it as a
scout.

No problem, you can handle the bugs you own. You're doing a great job at the
moment, don't hesitate.

Hi arches, alephone-20061228 is in the tree, thanks to nyhm.
Could you test it and mark stable if appropriate, please? thanks

x86 stable

I can't test this, on startup i simply get this:

However, the latest stable has exactly the same issue. Can someone else from
the amd64 team give it a try please?

You don't run it by alephone, but alephone.sh, instead.  AlephOne is only the
engine, it requires data to play.  We have one data ebuild in the tree already,
alephone-infinity, so you can merge that, then run "alephone.sh infinity" to
play^H^H^H^Htest. ;]

Thanks for the explanation Chris. Seems worky, marked stable.

thanks Simon and Chris, i vote mmm... i would vote a half-no.

also tending to vote no

closing without GLSA, feel free to reopen if you disagree
