R-programmeerimise p\u00f5hiversioonis, mis on suunatud statistilise t\u00f6\u00f6tlemise, andmeanal\u00fc\u00fcsi ja visualiseerimise probleemide lahendamisele, on avastatud kriitiline haavatavus (CVE-2024-27322), mis viib koodi t\u00e4itmisele, kui dekodeeritakse kontrollimata andmeid. Haavatavust saab kasutada spetsiaalselt vormindatud failide t\u00f6\u00f6tlemisel RDS (R Data Serialization) ja RDX formaatides, mida kasutatakse rakenduste vahel andmevahetuseks. Probleem on lahendatud R 4.4.0 v\u00e4ljal. Pakettide v\u00e4rskenduste v\u00e4ljaandmist saab j\u00e4lgida Debian, Ubuntu, RHEL, SUSE\/openSUSE, Fedora, Arch ja FreeBSD lehtedel. <\/p>\n

Haavatavus tuleneb readRDS funktsiooni t\u00f6\u00f6p\u00f5him\u00f5ttest, mida kasutatakse RDS ja RDX formaatides failide laadimiseks, mis v\u00f5imaldavad edastada R-sari objekte t\u00f6\u00f6tlemiseks teisele s\u00fcsteemile. Siseerimine v\u00f5imaldab j\u00e4\u00e4dvustada olekuid ja jagada andmestikke programmidest. RDS formaat v\u00f5imaldab hoida \u00fchte objekti, samas kui RDX formaat koos RDB failidega v\u00f5imaldab edastada mitme objekti andmeid. Probleem on seotud sellega, et RDS formaat toetab objekti koodi PROMSXP, mis on seotud Promise t\u00fc\u00fcbiga, mida kasutatakse v\u00e4ljendite m\u00e4\u00e4ratlemiseks, mis k\u00e4ivitatakse as\u00fcnkroonselt, kasutades seotud v\u00e4\u00e4rtusi. <\/p>\n

Deserialiseerimise ajal m\u00e4\u00e4ratakse Promise objekti jaoks kolm komponenti \u2014 Promise v\u00e4\u00e4rtus, v\u00e4ljendus ja keskkond. Kui Promise t\u00fc\u00fcbi jaoks pole eelnevalt arvutatud v\u00e4\u00e4rtust m\u00e4\u00e4ratud, arvutatakse see deserialiseerimise k\u00e4igus v\u00e4ljenduse t\u00e4itmise kaudu funktsiooni \u201eeval\u201d abil. Nii v\u00f5ib r\u00fcndaja saavutada suvalise R keeles koodi t\u00e4itmise, asendades selle v\u00e4ljendiga, mis on seotud nende arvutamata v\u00e4\u00e4rtustega RDS v\u00f5i RDX failides.
