<p>come si puo&#8217; notare, il prompt finale e&#8217; di amministratore<br />
[nota] per compilare l&#8217; exploit bisogna avere installati i sorgenti o almeno gli headers del kernel in esecuzione [/nota]</p>
<p>molte distribuzioni hanno gia&#8217; tappato la falla in qualche modo e pertanto potrebbe bastare un aggiornamento del kernel</p>
<p>in caso contrario esiste una soluzione temporanea che va pero&#8217; eseguita ad ogni riavvio della macchina. La si puo&#8217; trovare qui:<br />

anche in questo caso, scaricate, compilate ed eseguite</p>

			<content:encoded><![CDATA[<p>Per chi non lo sapesse avant-window-navigator e&#8217; una dock stile quella di OS X. I repository debian che conosco sono piuttosto obsoleti (mi pare che da ottobre non vengono aggiornati), quindi ho creato alcuni pacchetti deb dalla versione di sviluppo (awn 166 + extras 296). Se vi servono stanno <a href="http://www.mediafire.com/?4jfncmxy50d">qui</a></p>
<p>I file .deb vanno installati a manina con dpkg -i</p>
<p>WARNING: sono stati compilati su Debian/sid, li ho installati e almeno sui miei pc posso dire che funzionano (anche se qualche applet non va ancora a dovere).  Non ho idea se possano funzionare anche su ubuntu senza far esplodere tutto, in ogni caso per ubuntu mi pare che ci siano gia&#8217; dei repository esterni per awn.</p>
