PCP (Performance Co-Pilot) t\u00f6\u00f6riistas, mis kogub s\u00fcsteemi j\u00f5udluse statistikat (nt Cockpit'i liideses), on tuvastatud kaks haavatavust. Esimene haavatavus (CVE-2024-45770) esineb pmpost utiliidis, mis on m\u00f5eldud s\u00f5numite logisse edastamiseks ja mis teatud k\u00e4ivitusolukordades t\u00f6\u00f6tab k\u00f5rgendatud privileegidega. Haavatavuse \u00e4rakasutamine v\u00f5imaldab j\u00f5uda koodi t\u00e4itmiseni root \u00f5igustega, kuid r\u00fcnnaku teostamiseks on vajalik juurdep\u00e4\u00e4s PCP konto kaudu. R\u00fcnnaku olemus seisneb s\u00fcmboolse lingi asendamises faili \"\/var\/log\/pcp\/NOTICES\", kuhu salvestatakse andmeid root \u00f5igustega protsessist ilma failiga avamisel O_NOFOLLOW lippu kasutamata. <\/p>\n

Teine haavatavus PCP-s (CVE-2024-45769) m\u00f5jutab taustaprotsessi pcmd ja toob kaasa m\u00e4lu\u00fclesaamise, kui saadetakse spetsiaalselt vormindatud andmeid. Haavatavuse ohtu v\u00e4hendab asjaolu, et pcmd on vaikimisi keelatud v\u00f5rgup\u00e4ringud teistest s\u00fcsteemidest. Haavatavused on k\u00f5rvaldatud PCP v\u00e4ljaandes 6.3.1. Probleemid tuvastati SUSE projekti arendajate l\u00e4bi viidud auditite k\u00e4igus. <\/p>\n

Lisaks on pakendihalduris Nix, mida kasutatakse NixOS jaotises, avastatud haavatavus (CVE-2024-45593). See haavatavus v\u00f5imaldab spetsiaalselt kujundatud NAR (Nix Archive) formaadis failide v\u00e4ljav\u00f5tmisel kirjutada suvalistesse failis\u00fcsteemi aladesse, milleks on lubatud juurdep\u00e4\u00e4su\u00f5igused, millega k\u00e4ivitatakse t\u00f6\u00f6tleja (Nix taustprotsessi kasutamisel toimub v\u00e4ljav\u00f5te root \u00f5igustega). Probleem ilmnes Nix 2.24 haru puhul ja see on lahendatud versioonis 2.24.6. <\/p>\n

Lisaks v\u00f5ib mainida teate avaldamist kriitilise haavatavuse tuvastamisest, mis m\u00f5jutab GNU\/Linux ja v\u00f5imaldab kaugelt, ilma autentimiseta, k\u00e4itada koodi s\u00fcsteemis. Praegu ei ole probleemi olemuse ja sellega seotud alams\u00fcsteemide kohta mingit teavet, on vaid \u00f6eldud, et koos distribuutorite arendajatega kavatsetakse probleemi algaruanne avaldada 30. septembril ning t\u00e4ielik detailide aruanne 6. oktoobril. CVE numbrit probleemile veel ei ole. Probleemi tuvastanud teadlase v\u00e4itel on ettev\u00f5tted Canonical ja Red Hat m\u00e4\u00e4ranud haavatavale kriitilise ohtlikkuse taseme (9.9 skaalal 10).
