W bibliotece Libarchive, kt\u00f3ra oferuje funkcje do pracy z r\u00f3\u017cnymi formatami archiw\u00f3w i plik\u00f3w skompresowanych, zidentyfikowano podatno\u015bci prowadz\u0105ce do przepe\u0142nienia bufora podczas przetwarzania specjalnie przygotowanych archiw\u00f3w w formacie RAR. Podatno\u015bci wyst\u0119puj\u0105 w funkcjach execute_filter_audio (CVE-2024-48957) oraz execute_filter_delta (CVE-2024-48958) i s\u0105 spowodowane brakiem sprawdzenia, czy blok «src» mo\u017ce nak\u0142ada\u0107 si\u0119 na blok «dst» w uszkodzonych archiwach. <\/p>\n

Luki zosta\u0142y usuni\u0119te w wersji Libarchive 3.7.5, w kt\u00f3rej naprawiono r\u00f3wnie\u017c ponad dziesi\u0119\u0107 b\u0142\u0119d\u00f3w prowadz\u0105cych do przekroczenia granic bufora, dost\u0119pu do ju\u017c zwolnionej pami\u0119ci lub przepe\u0142nie\u0144 ca\u0142kowitych podczas przetwarzania plik\u00f3w w formatach cpio, lzop, rpm, zip, uu i rar. Poprawki s\u0105 oznaczone jako problemy z bezpiecze\u0144stwem, ale nie przypisano im identyfikator\u00f3w CVE. Na razie nie jest jasne, czy mo\u017cna wykorzysta\u0107 te problemy do wykonania kodu podczas przetwarzania specjalnie przygotowanych plik\u00f3w. <\/p>\n

Libarchive jest u\u017cywane jako zale\u017cno\u015b\u0107 w wielu popularnych pakietach, takich jak smbclient, flatpak, appstream, libappimage, dpdk, cmake, rpm, nix, pacman, elfutils, unrar, claws-mail, ark, epiphany, evince, vagrant, vlc, mpv, gvfs, fwupd, systemd (opcjonalnie) i file-roller (mened\u017cer archiw\u00f3w w GNOME). Mo\u017cna \u015bledzi\u0107 pojawianie si\u0119 aktualizacji w dystrybucjach na nast\u0119puj\u0105cych stronach: Debian, Ubuntu, RHEL, SUSE\/openSUSE, Fedora, Arch, FreeBSD.
