Libarchive'i raamatukogus, mis pakub funktsioone erinevate arhiivifailide ja kompressitud failide t\u00f6\u00f6tlemiseks, on avastatud haavatavusi, mis viivad m\u00e4lubuffri \u00fcletamiseni spetsiaalselt kujundatud RAR-formaadis arhiivide t\u00f6\u00f6tlemisel. Haavatavused on olemas funktsioonides execute_filter_audio (CVE-2024-48957) ja execute_filter_delta (CVE-2024-48958) ning need on p\u00f5hjustatud kontrolli puudumisest, et 'src' plokk v\u00f5ib kahjustatud arhiivides kattuda 'dst' plokiga. <\/p>\n

Haavatavused on k\u00f5rvaldatud Libarchive versioonis 3.7.5, kus on samuti parandatud \u00fcle kaheteistk\u00fcmne vea, mis p\u00f5hjustasid puhverpiiride \u00fcletamist, juba vabastatud m\u00e4lu juurde p\u00e4\u00e4semist v\u00f5i t\u00e4isarvude \u00fclevoolu cpio, lzop, rpm, zip, uu ja rar failide t\u00f6\u00f6tlemisel. Parandused on m\u00e4rgitud kui turbeprobleemid, kuid neile ei ole antud CVE-identifikaatoreid. Praegu ei ole selge, kas neid probleeme saab \u00e4ra kasutada koodi t\u00e4itmise korraldamiseks spetsiaalselt vormindatud failide t\u00f6\u00f6tlemisel. <\/p>\n

Libarchive'i kasutatakse s\u00f5ltuvusena paljudes populaarsetes pakettides, n\u00e4iteks smbclient, flatpak, appstream, libappimage, dpdk, cmake, rpm, nix, pacman, elfutils, unrar, claws-mail, ark, epiphany, evince, vagrant, vlc, mpv, gvfs, fwupd, systemd (valikuline) ja file-roller (arhivihaldur GNOME'is).
