Korrigerende utgivelser av APT-pakkeadministrasjonsverkt\u00f8yet er publisert, som adresserer s\u00e5rbarheten (CVE-2026-109518) som gj\u00f8r det mulig \u00e5 omg\u00e5 sjekken ved filopplasting og oppn\u00e5 kj\u00f8ring av egen kode med root-rettigheter. Totalt er det dannet 13 utgivelser, som dekker alle grener av APT opprettet de siste 10 \u00e5rene, fra 1.2.x. Oppdateringer av pakker som l\u00f8ser s\u00e5rbarheten er ogs\u00e5 allerede laget for forskjellige versjoner av Debian, Ubuntu og Deepin. I standardkonfigurasjonen p\u00e5virker problemet alle utgivelser fra og med Debian 12 og Ubuntu 22.04. Utnyttelse av eldre versjoner er mulig hvis parameteren Acquire::Retries settes til mer enn 0.<\/p>\n

En angriper som kan infiltrere HTTP-trafikken mellom brukeren og pakkerepositoriet under installasjonen av en pakke, kan oppn\u00e5 installasjon av en manipulert uverifisert variant av pakken, noe som gir ham root-rettigheter i systemet. Angrepet kan for eksempel utf\u00f8res gjennom kompromittering av speil, proxy-servere, tr\u00e5dl\u00f8se tilgangspunkter eller leverand\u00f8rporter. Rapporten om s\u00e5rbarheten nevner ikke detaljer, men oppgir kun at problemet skyldes feilaktig h\u00e5ndtering av harde lenker. If\u00f8lge patchen, der \u00e5pning av fil med flagget FileFd::Empty (O_TRUNC) er endret til FileFd::Exclusive (O_EXCL), kunne angriperen ved gjenopptakelse av en avbrutt nedlasting oppn\u00e5 omskrivning av data som allerede var hashet ved f\u00f8rste nedlasting.
