Kwiveki edlulileyo sipapashe inqaku apho sixele khona ukuba iCanonical ihlaziye i-Ubuntu kernel ukugubungela iimpazamo ezininzi zokhuseleko. Kwakukho iimpazamo ezininzi kunesiqhelo kolu hlobo lohlaziyo, kuyinto eqhelekileyo ukugubungela malunga ne-4-5. Kwiiyure ezimbalwa ezidlulileyo, inkampani iye yasungula enye Uhlaziyo lwe-kernel yoBuntu, kodwa ngeli xesha, nangona kusoloko kucetyiswa ukwamkela utshintsho, akungxamisekanga kangako.
Enyanisweni, kwiingxelo ezimbini, abaninzi abasebenzisi baxhalabele enye kuphela. Eyokuqala yi I-USN-5484-1, kwaye ilungisa iibhugi ezi-5 ezichaphazela Ubuntu 14.04. Siyakhumbula ukuba le nguqulo ye-Ubuntu, kunye neminyaka eyi-8 yobomi, ikwisigaba se-ESM, oko kukuthi, ukusebenzisa inkxaso eyandisiweyo apho iziphene zokhuseleko ze-kernel ziqhubeka zigutyungelwa. Enye ingxelo ithi I-USN-5485-1, kwaye lo kufuneka utsale ingqalelo kubasebenzisi abaninzi be-Ubuntu, ekubeni ichaphazela zonke iinguqulelo ezixhaswayo, kuquka i-16.04 kunye ne-14.04, leyo, njengoko sichazile, kwisigaba se-ESM.
Ubuntu bugubungela iibhugi ezintathu ezichaphazela zonke iinguqulelo zabo
Iibhugi ezintathu ezigutyungelwe kule ngxelo yamva nje kunye neenkcazo zazo zezi:
- I-CVE-2022-21123-Kwafunyaniswa ukuba ezinye iiprosesa ze-Intel azizange zizenze ngokupheleleyo izenzo zokucoca kwii-buffers ezabelwana ngazo ezininzi. Umhlaseli wasekuhlaleni unokusebenzisa oku ukubonisa ulwazi olubuthathaka.
- I-CVE-2022-21125-Kwafunyaniswa ukuba ezinye iiprosesa ze-Intel azenzanga ngokupheleleyo izenzo zokucoca kwi-microarchitecture yokuzalisa iibuffers. Umhlaseli wasekuhlaleni unokusebenzisa oku ukuveza ulwazi olubuthathaka.
- I-CVE-2022-21166-Kwafunyaniswa ukuba ezinye iiprosesa ze-Intel azenzi ngokuchanekileyo ukucoca ngexesha lemisebenzi ethile yokubhala kwiirejista ezikhethekileyo. Umhlaseli wasekuhlaleni unokusebenzisa oku ukubonisa ulwazi olubuthathaka.
Ukuzikhusela kuzo zonke ezi zoyikiso, vula ngokulula iziko lesoftware yosasazo kwaye ufake iipakethe ezintsha zekernel. Banokufakwa ngokuvula i-terminal kwaye uchwetheze edumileyo «uhlaziyo lwe-sudo apt && sudo apt ukuphucula«. Nangona kuzo zontathu iimeko "umhlaseli wendawo" ukhankanyiwe, kungcono ukukhuselwa, kwaye ukuhlaziywa kubiza kancinci.
