Mva nje abafana kwiCanonical bakhuphe uhlaziyo kubungozi beSpectereyiphi ibangele ukungqubana okuninzi okoko kwaqala unyaka kunye neMeltdown bobabini banoxanduva lokuvumela abahlaseli ukuba bafikelele kulwazi oluyimfihlo ngenxa yoyilo lweeprosesa.
Ngaphambi koku I-Canonical ikhuphe olu hlaziyo lutsha lwe-microcode kubo bonke abasebenzisi be-Ubuntu abaneeprosesa ze-AMD Kwilinge lokuphelisa ukuba semngciphekweni kweSpecter V2 kuzo.
Olu bungozi kukhuseleko luchaphazela zonke ii-microprocessors ezisebenzisa umsebenzi wokuqikelela kwesebe kunye nokwenza into ecingelwayo. kwaye inokuvumela imemori engagunyaziswanga ukuba ifundwe ngohlaselo lweendlela ezisecaleni kwiinkqubo ezingakhange zifumane izilungiso ezichanekileyo.
Uhlaziyo olutsha lweeprosesa ze-AMD ngokuchasene neSpecterV2
Le ngxaki yafunyanwa nguJann Horn loluphi umahluko wesibini (I-CVE-2.017-5715) Wobungozi beSpecial obuchaza njengokuhlaselwa ngenaliti.
Ukulungisa ingxaki, uhlaziyo lwe-microcode firmware luyafuneka iprosesa kwaye ngoku, iCanonical yenze ukuba kufumaneke kubasebenzisi bayo ukuba babe neeprosesa ze-AMD kwiikhompyuter zabo.
Hlaziya iiphakheji I-microcode yee-CPU ze-AMD kuzo zonke iinguqulelo ze-Ubuntu ezixhaswayo zezi sele ikhona kubandakanya Ubuntu 18.04 LTS (Bionic Beaver), Ubuntu 17.10 (Artful Aardvark), Ubuntu 16.04 LTS (Xenial Xerus) kunye Ubuntu 14.04 LTS (Trusty Tahr).
I-Canonical yatsho Iphakheji ehlaziyiweyo ibonelela ngohlaziyo lwe-microcode kusapho lweprosesa ye-AMD 17H, Efunekayo kuhlaziyo lokhuseleko lweLinux Kernel ekhutshwe yinkampani kwezi veki zidlulileyo kuzo zonke izinto ezikhutshwe Ubuntu.
Abasebenzisi bacetyiswa ukuba bahlaziye iinkqubo zabo kwangokoAbasebenzisi be-Ubuntu 18.04 LTS kufuneka baphucule i-amd64-microcode-3.20180524.1 ~ ubuntu0.18.04.1Abasebenzisi be-Ubuntu 17.10 kufuneka baphucule ukuya i-amd64-microcode-3.20180524.1 ~ ubuntu0.17.10.1Abasebenzisi be-Ubuntu 16.04 LTS kuya kufuneka baphucule i-amd64-microcode-3.20180524.1 ~ ubuntu0.16.04.1 kunye ne-Ubuntu 14.04 LTS kufuneka ihlaziye i-amd64-microcode-3.20180524.1 ~ ubuntu0.14.04.1.
Ulufaka njani uhlaziyo ngokuchasene neSpecter V2?
Si ufuna ukufaka uhlaziyo ngokuchasene neSpecter V2 kuya kufuneka uvule i-terminal nge-Ctrl + Alt + T kwaye wenze nayiphi na le miyalelo ilandelayo ngokohlobo lwakho kunye noyilo lwenkqubo yakho.
Ezi phakheji zikwasebenza ngokuhanjiswa okususelwe ku-Ubuntu.
Ukufakwa kwi-Ubuntu 18.04 LTS
Kubasebenzisi benguqulelo yangoku ye-Ubuntu eyi-18.04 kunye Ine-64-bit yoyilo, kuya kufuneka uyenze le miyalelo:
