Vatsvakurudzi veSecurity vakaratidza kubatika uko kunogona kukanganisa Unix-based operating system, kusanganisira macOS Big Sur uye shanduro dzekare. Uku kushushikana kwesudo mu macOS kunogona kupa rombo rakanaka kune vashandisi vemuno.

MunaNdira, vaongorori vezvekuchengetedza vakaratidza kusagadzikana kutsva kunogona kukanganisa masisitimu anoshanda eUnix. Iko kushandisa kwave kuripo kweanenge makore gumi, zvisinei iyi ndiyo yekutanga inozivikanwa zvinyorwa zvacho. Inozivikanwa seCVE-2021-3156, Sudo yakavakirwa buffer inoputika. Iyo yekushandisa inoratidzika yakafanana neyaimbove bug chigamba chinonzi CVE-2019-18634. Vanotsvaga kubva Qualy's yakaratidza bug muUbuntu 20.04 (Sudo 1.8.31), Debian 10 (Sudo 1.8.27) uye Fedora 33 (Sudo 1.9.2). Vanoti zvinogona kukanganisa mamwe masisitimu anoshanda uye kugoverwa kuchimhanyisa vhezheni yeSudo. Ese mavhezheni enhoroondo 1.8.2 kusvika 1.8.31p2 uye ese akatsiga vhezheni 1.9.0 kusvika 1.9.5p1 anokanganiswa.
Ehe. Tinogona kuve takadzikama, nekuti sekureva kwevaongorori, vashandisi vachada mukana wekushandisa komputa kumhanyisa kushandisa. Chengetedzo Mutsvakurudzi Matthew Hickey, Co-Muvambi weHacker House akataura nezve ZDNet, zvakaburitswa neChitatu izvo iyo bug inogona zvakare kushandiswa paMac.
Kuti umise simba, iwe unongofanirwa kunyora pamusoro argv [0] kana kugadzira chinongedzo chekufananidza, nekudaro inofumura iyo inoshanda sisitimu kune imwecheteyo kunetseka yemuno midzi iyo yakakanganisa vashandisi veLinux kwevhiki rapfuura.

Apple inofanira kuvhura yekuchengetedzwa kugadzirisa pamwe nechigamba chero nguva, asi vashandisi vanogona kuita pakutanga kana tichiona zvichidikanwa. Ehezve, mushure mekubhadhara maQualys, ayo anopa chirongwa chinotsanangura maitiro ekubatisisa kusagadzikana. Hatitende kuti izvi zvinodikanwa, asi zvakare hazvina basa.
