Pubblicato<\/a><\/noindex> aggiornamento del sistema di caching dei dati in memoria Memcached 1.6.2<\/a><\/noindex>, nel quale \u00e8 stata corretta vulnerabilit\u00e0<\/a><\/noindex>, che consente di avviare un crash del flusso di lavoro inviando una richiesta appositamente formattata. La vulnerabilit\u00e0 si manifesta a partire dalla versione 1.6.0. Come soluzione alternativa per la protezione, \u00e8 possibile disabilitare il protocollo binario per le richieste esterne avviando con l'opzione «-B ascii».<\/p>\n

Il problema \u00e8 causato da un errore nel codice<\/a><\/noindex> parser del protocollo binario, relativo a una errata definizione della dimensione dei dati copiati nel buffer durante la chiamata della funzione memcpy (la dimensione \u00e8 determinata in base al parametro specificato nell'intestazione della richiesta). Attraverso manipolazioni del valore del parametro nell'intestazione del protocollo binario, un'attaccante in grado di connettersi alla porta di rete di Memcached pu\u00f2 innescare un overflow del buffer, causando un crash del processo di lavoro.<\/p>\n
