Publicerat<\/a><\/noindex> uppdatering av datacachningssystemet i minnet Memcached 1.6.2<\/a><\/noindex>, d\u00e4r man har \u00e5tg\u00e4rdat s\u00e5rbarhet<\/a><\/noindex>, vilket m\u00f6jligg\u00f6r att initiera ett arbetsfl\u00f6deskrasch genom att skicka en s\u00e4rskilt utformad f\u00f6rfr\u00e5gan. S\u00e5rbarheten upptr\u00e4der fr\u00e5n version 1.6.0 och som en tillf\u00e4llig skydds\u00e5tg\u00e4rd kan det vara m\u00f6jligt att st\u00e4nga av det bin\u00e4ra protokoll f\u00f6r externa f\u00f6rfr\u00e5gningar genom att k\u00f6ra med alternativet «-B ascii».<\/p>\n

Problemet orsakas av en bugg i koden<\/a><\/noindex> parseringen av rubriken f\u00f6r det bin\u00e4ra protokollet, relaterat till en felaktig definition av storleken p\u00e5 de data som kopieras till bufferten n\u00e4r funktionen memcpy anropas (storleken best\u00e4ms utifr\u00e5n parametern som anges i rubriken). Genom att manipulera v\u00e4rdet av parametern i rubriken f\u00f6r det bin\u00e4ra protokollet kan en angripare som har m\u00f6jlighet att ansluta till Memcached:s n\u00e4tverksport initiera en buffert\u00f6verskridning, vilket leder till en processkrasch.<\/p>\n
