I den pakkebaserede distribution af Ubuntu 26.10, der er planlagt til udgivelse den 15. oktober, er der gennemf\u00f8rt en fuldst\u00e6ndig overgang til v\u00e6rkt\u00f8jerne uutils coreutils (Rust Coreutils), som er skrevet i Rust. V\u00e6rkt\u00f8jerne fra Rust Coreutils har helt erstattet alle komponenter i pakken GNU Coreutils, herunder v\u00e6rkt\u00f8jerne cp, mv og rm, som i Ubuntu 26.04 blev leveret i version fra GNU Coreutils. <\/p>\n
Rust-coreutils-pakken blev oprindeligt inkluderet som standard i udgivelsen af Ubuntu 25.10, men i LTS-grenen af Ubuntu 26.04 blev der foretaget en tilbagerulning til leveringen af cp, mv og rm fra GNU Coreutils-s\u00e6ttet. Varianterne af cp, mv og rm blev genindf\u00f8rt p\u00e5 grund af sikkerhedsproblemer, der blev opdaget under en revision af kodebasen for Rust Coreutils. St\u00f8rstedelen af s\u00e5rbarhederne i Rust Coreutils skyldes tilstedev\u00e6relsen af en race-tilstand, der muligg\u00f8r \u00e6ndring af data efter validering, men f\u00f8r operationen udf\u00f8res (TOCTOU \u2014 Time-Of-Check-To-Time-Of-Use). Blandt andet muligg\u00f8r s\u00e5danne s\u00e5rbarheder at erstatte en fil med et symbolsk link mellem afslutningen p\u00e5 kontrol og begyndelsen af udf\u00f8relsen af operationen. <\/p>\n
I konteksten af brugen af v\u00e6rkt\u00f8jerne cp, mv og rm i systemscripts, der k\u00f8res med root-rettigheder, giver inds\u00e6ttelsen af et symbolsk link mulighed for at kopiere, overskrive eller slette vilk\u00e5rlige filer. For eksempel, n\u00e5r kataloger slettes rekursivt, kontrollerede v\u00e6rkt\u00f8jet rm f\u00f8rst alle kataloger og slettede dem derefter i omvendt r\u00e6kkef\u00f8lge ved at kalde funktionen rmdir(). Hvis man erstatter for\u00e6ldrekataloget med et symbolsk link umiddelbart efter at have kontrolleret dette katalog, men f\u00f8r kontrol af de indholdte underkataloger, kan man opn\u00e5 sletning af hvilket som helst katalog i systemet ved dagligt at k\u00f8re fra cron-scriptet \/etc\/cron.daily\/apport, der med root-rettigheder rekursivt sletter indholdet af kataloget \/var\/crash, som er skrivebeskyttet for alle brugere i systemet. \u0412 \u043f\u0430\u043a\u0435\u0442\u043d\u043e\u0439 \u0431\u0430\u0437\u0435 \u0434\u0438\u0441\u0442\u0440\u0438\u0431\u0443\u0442\u0438\u0432\u0430
