U upravitelju paketa Cargo, koji se koristi za upravljanje paketima i izgradnju projekata na jeziku Rust, otkrivene su dvije ranjivosti koje se mogu iskoristiti prilikom preuzimanja posebno oblikovanih paketa iz vanjskih repozitorija (tvrdnje su da korisnike slu\u017ebenog repozitorija crates.io ova problema nisu pogodila). Prva ranjivost (CVE-2022-36113) omogu\u0107ava prepisivanje prva dva bajta u bilo kojoj datoteci, koliko dopu\u0161taju trenutna prava pristupa. Druga ranjivost (CVE-2022-36114) mo\u017ee se koristiti za iscrpljivanje slobodnog prostora na disku. <\/p>\n

Ranjivosti \u0107e biti ispravljene u izdanju Rust 1.64, planiranom za 22. rujna. Ranjivostima je dodijeljena niska razina opasnosti, budu\u0107i da sli\u010dnu \u0161tetu prilikom kori\u0161tenja neprovjerenih paketa iz vanjskih repozitorija mo\u017ee uzrokovati i standardna mogu\u0107nost pokretanja vlastitih handlera iz prilo\u017eenih u paketu skripti za izgradnju ili proceduronalnih makroa. Me\u0111utim, spomenuti problemi se razlikuju po tome \u0161to se njihovo iskori\u0161tavanje doga\u0111a u fazi otkrivanja paketa nakon preuzimanja (bez izgradnje). <\/p>\n

Naime, nakon preuzimanja paketa, cargo raspakira njegov sadr\u017eaj u direktorij ~\/.cargo i sa\u010duva oznaku uspje\u0161nog raspakiranja u datoteci .cargo-ok. Su\u0161tina prve ranjivosti je da kreator paketa mo\u017ee unutar sadr\u017eaja smjestiti simboli\u010dku vezu s imenom .cargo-ok, \u0161to \u0107e rezultirati zapisom teksta 'ok' u datoteku na koju ta veza upu\u0107uje. <\/p>\n

Druga ranjivost uzrokovana je nedostatkom ograni\u010denja na veli\u010dinu podataka koji se izvla\u010de iz arhiva, \u0161to se mo\u017ee iskoristiti za stvaranje 'zip-bombi' (u arhivu se mogu smjestiti podaci koji omogu\u0107uju postizanje maksimalnog stepena kompresije za zip format - oko 28 milijuna puta, u tom slu\u010daju, na primjer, posebno pripremljeni zip-datoteka veli\u010dine 10 MB rezultirat \u0107e dekompresijom oko 281 TB podataka).
