Deweloperzy firmy Mozilla wydali nowe wersje przegl\u0105darek internetowych Firefox 74.0.1 oraz Firefox ESR 68.6.1. U\u017cytkownikom zaleca si\u0119 aktualizacj\u0119 przegl\u0105darek, poniewa\u017c w nowych wersjach naprawiono dwie podatno\u015bci dnia zerowego, kt\u00f3re s\u0105 wykorzystywane przez haker\u00f3w w praktyce.<\/p>\n

\"W<\/p>\n

Chodzi o podatno\u015bci CVE-2020-6819 oraz CVE-2020-6820, zwi\u0105zane z tym, jak Firefox zarz\u0105dza swoj\u0105 przestrzeni\u0105 pami\u0119ci. S\u0105 to tzw. podatno\u015bci wykorzystania pami\u0119ci po zwolnieniu, kt\u00f3re pozwalaj\u0105 hakerom umieszcza\u0107 dowolny kod w pami\u0119ci Firefox, aby nast\u0119pnie wykonywa\u0107 go w kontek\u015bcie przegl\u0105darki. Takie podatno\u015bci mog\u0105 by\u0107 wykorzystywane do zdalnego wykonania kodu na urz\u0105dzeniach ofiary.<\/p>\n

Szczeg\u00f3\u0142owe informacje na temat rzeczywistych atak\u00f3w z wykorzystaniem wymienionych podatno\u015bci nie s\u0105 ujawniane, co jest powszechn\u0105 praktyk\u0105 w\u015br\u00f3d dostawc\u00f3w oprogramowania oraz badaczy w dziedzinie bezpiecze\u0144stwa informacyjnego. Wynika to z faktu, \u017ce zazwyczaj wszyscy koncentruj\u0105 si\u0119 na jak najszybszym usuni\u0119ciu wykrytych problem\u00f3w i dostarczeniu poprawek u\u017cytkownikom, a dopiero p\u00f3\u017aniej prowadz\u0105 dok\u0142adniejsze dochodzenia w sprawie atak\u00f3w.<\/p>\n

Z dost\u0119pnych informacji wynika, \u017ce dochodzenie w sprawie atak\u00f3w zwi\u0105zanych z tymi podatno\u015bciami b\u0119d\u0105 prowadzi\u0107 wsp\u00f3lnie Mozilla oraz firma zajmuj\u0105ca si\u0119 bezpiecze\u0144stwem IT JMP Security, jak r\u00f3wnie\u017c badacz Francisco Alonso, kt\u00f3ry pierwszy odkry\u0142 problem. Badacz sugeruje, \u017ce usuni\u0119te w ostatniej aktualizacji Firefox podatno\u015bci mog\u0105 dotyczy\u0107 innych przegl\u0105darek, chocia\u017c nie s\u0105 znane przypadki, w kt\u00f3rych b\u0142\u0119dy by\u0142yby wykorzystywane przez haker\u00f3w w r\u00f3\u017cnych przegl\u0105darkach internetowych.<\/p>\n
