F\u00f6retaget Cisco har presenterat<\/a><\/noindex> Korrigerande utg\u00e5van av den fria antiviruspaketet ClamAV 0.101.3, d\u00e4r s\u00e5rbarheten som g\u00f6r det m\u00f6jligt att initiera en \u00f6verbelastningsattack via en specifikt utformad zip-bilaga har \u00e5tg\u00e4rdats. <\/p>\n

Problemet<\/a><\/noindex> \u00e4r en variant av icke-rekursiv \"zip-bomb\"<\/a><\/noindex>, vars upplockning kr\u00e4ver mycket tid och resurser. Metoden g\u00e5r ut p\u00e5 att placera data i arkivet som m\u00f6jligg\u00f6r maximal kompression f\u00f6r zip-formatet \u2013 omkring 28 miljoner g\u00e5nger. Till exempel, en specialtillverkad zip-fil p\u00e5 10 MB kommer att resultera i att omkring 281 TB data packas upp, medan 46 MB ger 4,5 PB. <\/p>\n

Dessutom har det nya utg\u00e5van uppdaterat det inbyggda biblioteket libmspack, d\u00e4r flera s\u00e5rbarheter har \u00e5tg\u00e4rdats:<\/a><\/noindex> buffer\u00f6verskott (CVE-2019-1010305<\/a><\/noindex>), vilket leder till datal\u00e4ckage vid \u00f6ppning av en s\u00e4rskilt formaterad chm-fil.<\/p>\n

Samtidigt lanserades en beta-version av den nya ClamAV 0.102-grenen, d\u00e4r funktionaliteten f\u00f6r transparent filskanning (on-access scanning, kontroll vid \u00f6ppning av fil) har flyttats fr\u00e5n clamd till en separat process clamonacc, implementerad p\u00e5 liknande s\u00e4tt som clamdscan och clamav-milter. Denna \u00e4ndring har gjort det m\u00f6jligt att k\u00f6ra clamd under en vanlig anv\u00e4ndare utan att beh\u00f6va f\u00e5 root-beh\u00f6righeter.
\nI den nya grenen har st\u00f6d f\u00f6r egg-arkiv (ESTsoft) ocks\u00e5 lagts till och programmet freshclam har reviderats avsev\u00e4rt, med till\u00e4gget av st\u00f6d f\u00f6r HTTPS och m\u00f6jligheten att arbeta med speglar som hanterar beg\u00e4rningar p\u00e5 n\u00e4tverksportar som skiljer sig fr\u00e5n 80. <\/p>\n
