In der Bibliothek Libarchive, die Funktionen f\u00fcr die Arbeit mit verschiedenen Archivformaten und komprimierten Dateien bereitstellt, wurden Schwachstellen entdeckt, die zu Buffer-\u00dcberl\u00e4ufen bei der Verarbeitung speziell gestalteter Archive im RAR-Format f\u00fchren. Die Schwachstellen sind in den Funktionen execute_filter_audio (CVE-2024-48957) und execute_filter_delta (CVE-2024-48958) vorhanden und resultieren aus fehlenden \u00dcberpr\u00fcfungen, dass der Block «src» den Block «dst» in besch\u00e4digten Archiven \u00fcberschreiben kann. <\/p>\n

Die Sicherheitsanf\u00e4lligkeiten wurden in der Version Libarchive 3.7.5 behoben, die auch mehr als ein Dutzend Fehler korrigiert, die zu Puffer\u00fcberl\u00e4ufen, Zugriff auf bereits freigegebenen Speicher oder ganzzahligen \u00dcberl\u00e4ufen bei der Verarbeitung von Dateien in den Formaten cpio, lzop, rpm, zip, uu und rar f\u00fchren. Die Korrekturen sind als Sicherheitsprobleme gekennzeichnet, jedoch ohne die Zuweisung von CVE-IDs. Es ist noch unklar, ob diese Probleme ausgenutzt werden k\u00f6nnen, um die Ausf\u00fchrung von Code bei der Verarbeitung speziell gestalteter Dateien zu erm\u00f6glichen. <\/p>\n

Libarchive wird als Abh\u00e4ngigkeit in vielen popul\u00e4ren Paketen verwendet, zum Beispiel in smbclient, flatpak, appstream, libappimage, dpdk, cmake, rpm, nix, pacman, elfutils, unrar, claws-mail, ark, epiphany, evince, vagrant, vlc, mpv, gvfs, fwupd, systemd (optional) und file-roller (Archivmanager in GNOME). Updates in den Distributionen k\u00f6nnen auf den folgenden Seiten verfolgt werden: Debian, Ubuntu, RHEL, SUSE\/openSUSE, Fedora, Arch, FreeBSD.
