Ukulungiswa komzuzu wokugcina kukhishwa kusibuyekezo se-Ubuntu 14.04

Muva nje Ithimba lokuthuthukiswa kweCanonical likhiphe esinye sezibuyekezo ezijwayelekile ezivame ukwamukela izinhlobo zazo ze-LTS, kulokhu ikakhulukazi i-Ubuntu 14.04 LTS Trusty Tahr.

Lezi izibuyekezo zinokulungiswa kwamaphutha futhi ikakhulukazi ama-patches wezokuphepha we-kernel yohlelo.

ICanonical ikhiphe ukulungiswa okusha futhi yaxolisa ngalezi zinkinga ezingenhla akhiqizelwe abanye abasebenzisi benye yezinguqulo zabo ze-LTS ze-Ubuntu.

Kutholakale amaphutha amasha weSpecter amasha nawo athinta amaprosesa we-Intel's x86. Babizwa nge-Terminal Failure F1 (L1TF) noma iForeshadow.

Mayelana namaphutha atholiwe

Isibuyekezo sokuphepha seKernel sixazulula ukukhubazeka okubili okukuthi iyiphi yazo Ukuhluleka kokugcina kwe-F1, kanye namanye amaphutha amabili okuphepha (I-CVE-2018-5390 ne-CVE-2018-5391) itholwe nguJuha-Matti Tilli ekusetshenzisweni kwe-TCP ne-IP kernel ye-Linux, engavumela abahlaseli ukuthi babangele ukwenqatshwa kwenkonzo.

En Isitatimende seCanonical sabelane ngokulandelayo:

Kutholwe ukuthi imemori ekhona kunqolobane yedatha ye-L1 ye-Intel CPU ingavezwa kunqubo enonya esebenza ku-CPU.

Lokhu kuba sengozini kwaziwa nangokuthi yi-L1 Terminal Bug (L1TF). Lapho umhlaseli wendawo kumshini obonakalayo wezivakashi angasebenzisa lokhu ukudalula imininingwane (inkumbulo evela kwezinye izivakashi noma isistimu yokusebenza ye-Host). (I-CVE-2.018 kuya ku-3.646)

UJuha-Matti Tilli uthole ukuthi uhlelo lwe-IP ku-Linux kernel lwenza ukusebenza kwezinye izimo ekuphatheni izingcezu zepakethe ezingenayo. Umhlaseli okukude angasebenzisa lokhu ukudala ukunqatshelwa kwensizakalo. (CVE-2.018 kuya ku-5391)

Njengoba kuzoba njalo, lokhu kulungiswa kwamaphutha ezokuphepha kuzoxazululwa ngokukhululwa kwezimagqabhagqabha zokuphepha kubo.

Ngeshwa, ezinhlelweni ze-Ubuntu 14.04 LTS (Trusty Tahr), abasebenzisi babike lokho ukulungiswa kuye kwaletha ukubuyela emuva kumaphakheji we-linux kernel, okungadala i- "Kernel Panic" edumile yabasebenzisi abathile lapho beqala uhlelo lokusebenza ezindaweni ezithile zedeskithophu.

“Ngeshwa, isibuyekezo sethule ukuhlehla okwadala ukushayisana kwe-kernel ngesikhathi sokuqalisa kwezinye izindawo, futhi kwavimbela izinhlelo ze-java ukuqala. Lesi sibuyekezo silungisa izingqinamba. Siyaxolisa ngokungalungile.

Ngokunikezwa kwale mibono ngabasebenzisi bale nguqulo ye-Ubuntu 14.04 LTS, abakwaCanonical bekufanele bathathe izinyathelo ngalolu daba futhi kufanele baxazulule inkinga ngokushesha.

Lapho kukhishwe inguqulo entsha elungisiwe yeLinux Kernel, yabasebenzisi be-Ubuntu 14.04 LTS Trusty Tahr, icela bonke abasebenzisi ukuthi bavuselele izikhungo zabo ngokushesha okukhulu.

Ungaxhumana nesitatimende, Kulesi sixhumanisi esilandelayo.

Ukuvuselelwa kwe-Ubuntu 14.04 LTS

Njengoba kushiwo, le bug ithinta ngqo labo abangabasebenzisi be-Ubuntu 14.04 LTS kanjalo kudingekile kakhulu ukuthi bavuselele ngokushesha, lokhu ngenzela ukugwema ukuthi lokhu kwehluleka kuthinte uhlelo.

Ukuvuselelwa kungenziwa kalula.

Bangayenza kusuka esigungwini ngokwenza imiyalo elandelayo:

sudo apt-get update

sudo apt-get upgrade

sudo apt-get dist upgrade

Lapho lokhu sekwenziwe, uhlelo kufanele luqale ukubuyekeza amaphakheji, kanye neKernel yohlelo, ukulanda nokufaka ukulungiswa okwethulwe ngokusemthethweni.

Ngendlela efanayo ongakwenza ngayo lokhu ngokomfanekiso, uthayipha esigungwini:

update-manager

Futhi lokhu kuzobakhombisa izibuyekezo ezihambisanayo futhi kuzodingeka ukuthi bamukele futhi bafake kuphela.

Ngemuva kokuvuselelwa kwe-kernel ejwayelekile, kunconywa ukuthi abasebenzisi baqale kabusha imishini yabo futhi, uma kunesidingo, baphinde bahlanganise wonke amamojula we-kernel angafakwa, uma beyikhiphe ngesandla i-kernel.

Ngendlela efanayo, ungaxhumana nemiyalo enikezwe yi-Canonical ukuze ukwazi ukwenza isibuyekezo esilula futhi esiphephile kusuka kusistimu yakho.

Isixhumanisi yilokhu.
