Valmistatud on Samba paketid 4.14.4, 4.13.8 ja 4.12.15 parandustega, mis k\u00f5rvaldab haavatavuse (CVE-2021-20254). See v\u00f5ib enamasti p\u00f5hjustada smbd protsessi kokkujooksmise, kuid halvemal juhul ei saa v\u00e4listada mitteautoriseeritud juurdep\u00e4\u00e4su failidele ja privileegide puudumise t\u00f5ttu failide kustutamist v\u00f5rgukaustas. <\/p>\n
Haavatavus tuleneb veast sids_to_unixids() funktsioonis, mis p\u00f5hjustab m\u00e4lust andmete lugemist, kui muudetakse SID (Windows Security Identifier) grupi identifikaatoreid GID (Unix Group ID) vormingusse. Probleem tekib juhul, kui negatiivne element lisatakse SID ja GID vastenduste vahem\u00e4llu. Samba arendajad ei suutnud tuvastada usaldusv\u00e4\u00e4rseid ja korduvaid tingimusi, mis k\u00e4ivitaksid haavatavuse, kuid selle avastanud teadlane usub, et probleem v\u00f5ib olla ekspluateeritav failide kustutamiseks. serveril<\/a> ilma sobivate \u00f5igusteta selle toimingu tegemiseks. \u041f\u043e\u0434\u0433\u043e\u0442\u043e\u0432\u043b\u0435\u043d\u044b
