Muva nje abafana baseCanonical bakhiphe isibuyekezo ebungozini beSpecter, okuyinto kubangele ukuxokozela okuningi selokhu kuqale unyaka kanye neMeltdown bobabili banesibopho sokuvumela abahlaseli ukufinyelela kulwazi oluyimfihlo ngenxa yamaphutha wokuklama kubaprosesa.
Ngaphambi kwalokhu ICanonical ikhiphe lesi sibuyekezo esisha se-microcode sabo bonke abasebenzisi be-Ubuntu abanezinqubo ze-AMD ngemizamo yokuqeda ukuba sengozini kwe-Specter V2 kuzo.
Lokhu kuba sengozini kokuphepha kuthinta wonke ama-microprocessor asebenzisa umsebenzi wokubikezela kwegatsha nokwenza okuqagelayo. futhi ingavumela imemori engagunyaziwe ifundwe ngokuhlaselwa kwesiteshi eseceleni kumasistimu angakatholi ukulungiswa okulungile.
Isibuyekezo esisha samaprosesa we-AMD ngokumelene ne-SpecterV2
Le nkinga yatholwa uJann Horn okuhlukile kwesibili (I-CVE-2.017-5715) Wobungozi beSpecter obuchaza njengokuhlaselwa ngomjovo.
Ukulungisa inkinga, kudingeka isibuyekezo se-microcode firmware processor manje, iCanonical yenze ukuthi kutholakale kubasebenzisi bayo ukuthi babe nezinqubo ze-AMD kumakhompyutha abo.
Buyekeza amaphakheji i-microcode yama-AMD CPUs kuzo zonke izinhlobo ze-Ubuntu ezisekelwayo isivele itholakale kufaka phakathi Ubuntu 18.04 LTS (Bionic Beaver), Ubuntu 17.10 (Artful Aardvark), Ubuntu 16.04 LTS (Xenial Xerus) kanye Ubuntu 14.04 LTS (Trusty Tahr).
UCanonical ukusho lokho Iphakheji ebuyekeziwe inikezela ngezibuyekezo ze-microcode zomndeni weprosesa we-AMD 17H, okudingeka izibuyekezo zokuphepha zeLinux Kernel inkampani ekhishwe emasontweni adlule kukho konke ukukhishwa Ubuntu.
Abasebenzisi banconywa ukuthi bavuselele amasistimu abo ngokusheshaAbasebenzisi be-Ubuntu 18.04 LTS kufanele bathuthukele ku- amd64-microcode - 3.20180524.1 ~ ubuntu0.18.04.1Abasebenzisi be-Ubuntu 17.10 kufanele bathuthukele ku- amd64-microcode - 3.20180524.1 ~ ubuntu0.17.10.1Abasebenzisi be-Ubuntu 16.04 LTS kuzofanele bathuthukele ku- amd64-microcode - 3.20180524.1 ~ ubuntu0.16.04.1 futhi Ubuntu 14.04 LTS kufanele ivuselele ku- amd64-microcode - 3.20180524.1 ~ ubuntu0.14.04.1.
Ungasifaka kanjani isibuyekezo ngokumelene ne-Specter V2?
Si ufuna ukufaka isibuyekezo ngokumelene ne-Specter V2 kufanele uvule i-terminal nge-Ctrl + Alt + T bese wenza noma imiphi yale miyalo elandelayo ngokwenguqulo yakho nokwakhiwa kwesistimu yakho.
Lawa mapakeji asebenza futhi ekusatshalalisweni okususelwe ku-Ubuntu.
Ukufaka ku-Ubuntu 18.04 LTS
Okwabasebenzisi benguqulo yamanje ye-Ubuntu eyi-18.04 ne Inokwakhiwa okungama-64-bit, kufanele usebenzise le miyalo:
