Firma Cisco przedstawi\u0142a<\/a><\/noindex> poprawki w bezp\u0142atnym pakiecie antywirusowym ClamAV 0.101.3, kt\u00f3ry eliminuje luk\u0119 umo\u017cliwiaj\u0105c\u0105 przeprowadzenie ataku typu DoS poprzez przes\u0142anie specjalnie przygotowanego archiwum zip jako za\u0142\u0105cznika. <\/p>\n

Problem<\/a><\/noindex> jest wariantem nierekurencyjnej \u201ebomby zip\u201d<\/a><\/noindex>, kt\u00f3rej rozpakowanie wymaga bardzo du\u017cej ilo\u015bci czasu i zasob\u00f3w. Istota metody polega na umieszczaniu w archiwum danych, kt\u00f3re pozwalaj\u0105 osi\u0105gn\u0105\u0107 maksymalne dla formatu zip stopie\u0144 kompresji \u2014 oko\u0142o 28 mln razy. Na przyk\u0142ad specjalnie przygotowany plik zip o rozmiarze 10 MB spowoduje rozpakowanie oko\u0142o 281 TB danych, a 46 MB \u2014 4.5 PB. <\/p>\n

Ponadto w nowej wersji zaktualizowano bibliotek\u0119 libmspack, w kt\u00f3rej usuni\u0119to<\/a><\/noindex> przepe\u0142nienie bufora (CVE-2019-1010305<\/a><\/noindex>), prowadz\u0105ce do wycieku danych podczas otwierania specjalnie skonfigurowanego pliku chm.<\/p>\n

R\u00f3wnocze\u015bnie wprowadzono wersj\u0119 beta nowej ga\u0142\u0119zi ClamAV 0.102, w kt\u00f3rej funkcjonalno\u015b\u0107 transparentnego skanowania otwieranych plik\u00f3w (skanowanie w momencie otwierania pliku) zosta\u0142a przeniesiona z clamd do osobnego procesu clamonacc, zrealizowanego na wz\u00f3r clamdscan i clamav-milter. Zmiana ta umo\u017cliwi\u0142a dzia\u0142anie clamd pod zwyk\u0142ym u\u017cytkownikiem bez konieczno\u015bci uzyskiwania praw roota.
\nW nowej wersji dodano r\u00f3wnie\u017c wsparcie dla archiw\u00f3w egg (ESTsoft) oraz znacz\u0105co przebudowano program freshclam, w kt\u00f3rym pojawi\u0142o si\u0119 wsparcie dla HTTPS oraz mo\u017cliwo\u015b\u0107 pracy z lustrami obs\u0142uguj\u0105cymi zapytania na r\u00f3\u017cnych portach sieciowych, r\u00f3\u017cni\u0105cych si\u0119 od 80. <\/p>\n
