In de pakketbasis van de Ubuntu 26.10-distributie, waarvan de release is gepland voor 15 oktober, is er een volledige overgang gemaakt naar de toolset uutils coreutils (Rust Coreutils), geschreven in de programmeertaal Rust. De tools van Rust Coreutils hebben alle componenten van het GNU Coreutils-pakket volledig vervangen, inclusief de tools cp, mv en rm, die in Ubuntu 26.04 werden geleverd vanuit de GNU Coreutils. <\/p>\n

Het rust-coreutils pakket was oorspronkelijk standaard opgenomen in de release van Ubuntu 25.10, maar in de LTS-tak van Ubuntu 26.04 is er een terugdraaiing gedaan naar het aanbieden van de cp, mv en rm utiliteiten uit de GNU Coreutils set. De varianten cp, mv en rm zijn opnieuw ge\u00efntroduceerd vanwege beveiligingsproblemen die naar voren kwamen tijdens de audit van de Rust Coreutils codebasis. De meeste kwetsbaarheden in Rust Coreutils zijn veroorzaakt door een raceconditie, die het mogelijk maakt om gegevens te wijzigen op het moment dat de correctheid van de informatie is gecontroleerd, maar voordat de operatie op hen wordt uitgevoerd (TOCTOU \u2014 Time-Of-Check-To-Time-Of-Use). Onder andere kunnen dergelijke kwetsbaarheden het mogelijk maken om een bestand te vervangen door een symbolische link in het moment tussen het voltooien van de controle en het starten van de uitvoering van de operatie. <\/p>\n

In de context van het gebruik van de tools cp, mv en rm in systeemscripties, uitgevoerd met root-rechten, biedt het invoegen van een symbolische link de mogelijkheid om willekeurige bestanden te kopi\u00ebren, te overschrijven of te verwijderen. Bijvoorbeeld, bij het recursief verwijderen van mappen controleerde de rm-tool eerst alle mappen en verwijderde ze vervolgens in omgekeerde volgorde door de functie rmdir() aan te roepen. Als de bovenliggende map onmiddellijk na de controle van deze map wordt vervangen door een symbolische link, maar v\u00f3\u00f3r de controle van de daarin opgenomen submappen, kan elke map in het systeem worden verwijderd bij dagelijkse uitvoering vanuit het cron-script \/etc\/cron.daily\/apport, dat met root-rechten recursief de inhoud van de map \/var\/crash verwijdert, die voor alle gebruikers in het systeem schrijfbaar is.
