GNOME'i projekti arendatav libgsf raamatukogu avastas haavatavuse (CVE-2024-42415), mis v\u00f5ib p\u00f5hjustada kodeerimise t\u00e4itmist spetsiaalselt kujundatud faili t\u00f6\u00f6tlemisel. Haavatavus tuleneb t\u00e4isarvude \u00fclevoolust, mis viib andmete kirjutamiseni eraldatud puut\u00fcki piirist v\u00e4ljas, kui t\u00f6\u00f6deldakse sektorite jaotustabelit, parseerides parameetreid CDF (Compound Document Format) failivormingu p\u00e4isest. <\/p>\n

Libgsf raamatukogu pakub funktsioone erinevate struktureeritud failivormingute, sealhulgas arhiivide ja dokumendifailide, t\u00f6\u00f6tlemiseks. Lisaks rakendustele nagu AbiWord, Gnumeric, GNOME Commander ja Nemo, kasutatakse raamatukogu GNOME'i projektis otsingumootoris tracker-miners ning see on s\u00f5ltuvus paketist tracker-extract, mis automaatselt kogub uute failide metainfot. <\/p>\n

Oht on selles, et GNOME teenus, mis kasutab libgsf, indekseerib ja anal\u00fc\u00fcsib automaatselt k\u00f5iki faile kodukataloogis ilma kasutaja sekkumiseta. Seega, et r\u00fcnnakule v\u00f5imalus anda, on vajalik, et kasutaja katalooge ilmuks spetsiaalselt loodud fail (n\u00e4iteks m\u00f5nel juhul piisab faili saamiseks kataloogist ~\/Downloads, kui brauseris kl\u00f5psata lihtsalt lingil) ning haavatavust \u00e4ra kasutatakse selle automaatse indekseerimise ajal. <\/p>\n

Haavatavus on k\u00f5rvaldatud raamatukogu libgsf versioonis 1.14.53. Uuenduste ilmumist distributsioonides saab j\u00e4lgida j\u00e4rgmistelt lehtedelt: Debian, Ubuntu, RHEL, SUSE\/openSUSE, Fedora, Arch, FreeBSD. Enamikes GNOME distributsioonidest aktiveeritakse komponent tracker-miners vaikimisi ja see laetakse koos failihalduriga Nautilus (GNOME Files) rangelt s\u00f5ltuvusena. Tracker-miners'i keelamiseks praeguse kasutaja jaoks saab kasutada j\u00e4rgmisi k\u00e4ske: systemctl --user mask tracker-store.service tracker-miner-fs.service tracker-miner-rss.service tracker-extract.service tracker-miner-apps.service tracker-writeback.service tracker reset --hard
