Dhawaan ragga ku jira Canonical waxay soo saareen cusbooneysiin ku saabsan u nuglaanta Specter, taas oo wuxuu sababay jahwareer badan tan iyo bilowgii sanadka oo ay weheliso Meltdown labaduba waxay mas'uul ka yihiin u oggolaanshaha kuwa wax weeraraya inay helaan macluumaad qarsoodi ah cilladaha naqshadeynta ee ku jira processor-ka.
Tan ka hor Canonical wuxuu sii daayay cusbooneysiintan cusub ee microcode dhammaan isticmaaleyaasha Ubuntu ee haysta processor-yada AMD isku day ah in laga takhaluso nuglaanta Specter V2 ee ku jirta.
Jilicsanaanta nabadgelyadu waxay saameysaa dhammaan microprocessors-ka adeegsada saadaasha laanta iyo fulinta mala-awaalka. oo waxay u oggolaan kartaa xusuusta aan la oggoleyn ee lagu akhriyo weerarada dhinac-kanal ee nidaamyada aan helin saxitaanka saxda ah.
Cusbooneysiin cusub oo loogu talagalay processor-yada AMD ee ka dhanka ah SpecterV2
Dhibaatadaas waxaa daahfuray Jann Horn taas oo ah nooca labaadCVE-2.017-5715) ee u nuglaanta 'Specter' taas oo ay ku tilmaamayso weerar cirbad.
Si loo saxo dhibaatada, waxaa loo baahan yahay cusbooneysiin firmware microcode ah processor-ka iyo hadda, Canonical wuxuu u diyaariyey isticmaaleyaashiisa inay ku hayaan processor-yada AMD kumbuyuutarradooda.
Cusboonaysii xirmooyinka microcode loogu talagalay AMD CPUs dhammaan noocyada Ubuntu ay taageerayaan waa horeyba loo heli jiray oo ay ku jiraan Ubuntu 18.04 LTS (Bionic Beaver), Ubuntu 17.10 (Artful Aardvark), Ubuntu 16.04 LTS (Xenial Xerus) iyo Ubuntu 14.04 LTS (Trusty Tahr).
Canonical ayaa yiri xirmada la cusbooneysiiyay waxay bixisaa cusbooneysiinta microcode ee qoyska processor-ka AMD 17H, taas oo looga baahan yahay cusbooneysiinta amniga Linux Kernel ee shirkaddu sii deysay toddobaadyadii la soo dhaafay dhammaan sii deynta Ubuntu.
Isticmaalayaasha waxaa lagula talinayaa inay si dhakhso leh u cusbooneysiiyaan nidaamyadooda, Ubuntu 18.04 LTS isticmaalayaashu waa inay u cusbooneysiiyaan amd64-microcode - 3.20180524.1 ~ ubuntu0.18.04.1Ubuntu 17.10 adeegsadeyaashu waa inay cusbooneysiiyaan amd64-microcode - 3.20180524.1 ~ ubuntu0.17.10.1, Ubuntu 16.04 LTS isticmaalayaashu waa inay u cusbooneysiiyaan amd64-microcode - 3.20180524.1 ~ ubuntu0.16.04.1 iyo Ubuntu 14.04 LTS waa inay cusbooneysiiyaan amd64-microcode - 3.20180524.1 ~ ubuntu0.14.04.1.
Sidee loo rakibaa cusbooneysiinta Specter V2?
Si waxaad dooneysaa inaad ku dhejiso cusbooneysiinta Specter V2 waa inaad ka furtaa terminal Ctrl + Alt + T oo aad ku fulisaa mid ka mid ah amarradan soo socda iyadoo loo eegayo noocaaga iyo qaab dhismeedka nidaamkaaga.
Xirmooyinkaani sidoo kale waxay ansax u yihiin qaybinta laga soo qaatay Ubuntu.
Ku rakibida Ubuntu 18.04 LTS
Isticmaalayaasha nooca hadda jira ee Ubuntu oo ah 18.04 iyo Waxay leedahay qaab dhismeed 64-bit ah, waa inaad fulisaa amarradan:
wget https://launchpad.net/~ubuntu-security-proposed/+archive/ubuntu/ppa/+build/14953007/+files/amd64-microcode_3.20180524.1~ubuntu0.18.04.1_amd64.deb sudo dpkg -i amd64-microcode_3.20180524.1~ubuntu0.18.04.1_amd64.deb
Si nidaamkaagu waa 32 jajab waa inaad ku qortaa amarradan:
wget https://launchpad.net/~ubuntu-security-proposed/+archive/ubuntu/ppa/+build/14953008/+files/amd64-microcode_3.20180524.1~ubuntu0.18.04.1_i386.deb sudo dpkg -i amd64-microcode_3.20180524.1~ubuntu0.18.04.1_i386.deb
Ku rakibida Ubuntu 17.10
Hada hadaad wali isticmaaleyso noocii hore ee ahaa Ubuntu 17.10 oo nidaamkaagu waa 64 jajab waa inaad qortaa:
wget https://launchpad.net/~ubuntu-security-proposed/+archive/ubuntu/ppa/+build/14953014/+files/amd64-microcode_3.20180524.1~ubuntu0.17.10.1_amd64.deb sudo dpkg -i amd64-microcode_3.20180524.1~ubuntu0.17.10.1_amd64.deb
Oo haa nidaamkaagu waa 32 bit amarku waa kan:
wget https://launchpad.net/~ubuntu-security-proposed/+archive/ubuntu/ppa/+build/14953015/+files/amd64-microcode_3.20180524.1~ubuntu0.17.10.1_i386.deb sudo dpkg -i amd64-microcode_3.20180524.1~ubuntu0.17.10.1_i386.deb
Ku rakibida Ubuntu 16.04 LTS
Dhinaca kale, haddii aad wali isticmaaleyso nooca Ubuntu 16.04 LTS waana nidaamkaaga 64-bit waa inaad qortaa amarkan:
wget https://launchpad.net/~ubuntu-security-proposed/+archive/ubuntu/ppa/+build/14953071/+files/amd64-microcode_3.20180524.1~ubuntu0.16.04.1_amd64.deb sudo dpkg -i amd64-microcode_3.20180524.1~ubuntu0.16.04.1_amd64.deb
Ama haddii ay isticmaalayaan Nooca 32-bit waa inuu adeegsadaa amarkan:
wget https://launchpad.net/~ubuntu-security-proposed/+archive/ubuntu/ppa/+build/14953072/+files/amd64-microcode_3.20180524.1~ubuntu0.16.04.1_i386.deb sudo dpkg -i amd64-microcode_3.20180524.1~ubuntu0.16.04.1_i386.deb
Ku rakibida Ubuntu 14.04 LTS
Ugu dambeyntii nooca ugu dambeeya ee leh taageerada taasi waa Ubuntu 14.04 LTS waa inay soo dejiso xirmadan haddii ay leeyihiin qaab dhismeed 64-bit ah:
wget https://launchpad.net/~ubuntu-security-proposed/+archive/ubuntu/ppa/+build/14954344/+files/amd64-microcode_3.20180524.1~ubuntu0.14.04.1_amd64.deb sudo dpkg -i amd64-microcode_3.20180524.1~ubuntu0.14.04.1_amd64.deb
Taas bedelkeedana way adeegsanayaan nooca 32 bit ee Ubuntu 14.04 LTS amarku waa kan:
wget https://launchpad.net/~ubuntu-security-proposed/+archive/ubuntu/ppa/+build/14954345/+files/amd64-microcode_3.20180524.1~ubuntu0.14.04.1_i386.deb sudo dpkg -i amd64-microcode_3.20180524.1~ubuntu0.14.04.1_i386.deb
Markaad dhamayso rakibaadda, waxaa aad loogu baahan yahay inaad dib u bilowdo kombiyuutaradaada si isbedelada lagu sameeyay nidaamka loo keydiyo oo aad kumbiyuutarrada ugu bilowdo cusbooneysiinta cusub.
Taasna, waxaad ku cusbooneysiin doontaa qalabkaaga lagana ilaalin doonaa noocyadan cusub.
Haddii aad rabto inaad ka ogaato faahfaahin dheeraad ah oo ku saabsan bayaankan waad booqan kartaa xiriirka soo socda. In kastoo, sidaan ognahay, uusan jirin nidaam amni ah, laakiin ma aha wax aad u xun in la cusbooneysiiyo oo sidaas looga fogaado dhibaatooyinka la yaqaan.
