I-Canonical isungule Inguqulelo entsha ye-kernel Ubuntu 18.04. Okanye kulungile, yile nto sinokuyifunda ukuba sijonga ulwazi malunga neLinux 5.0.0-23.24, uguqulelo oluhambelana nohlaziyo olukhutshwe izolo: iphepha elisemthethweni Ubuntu ubeka Inguqulelo echaphazelekayo yiBionic Beaver, kodwa uhlaziyo lukwafumaneka kwiDisco Dingo. Okucacileyo kukuba le nguqulo intsha ikhutshelwe i-Ubuntu 18.04 LTS ukuba usebenzisa iLinux 5.0.x.
Into ecace gca yile yile ilungisiweyo ichanekileyo kule nguqulo: Iimpazamo ezi-4 zokhuseleko isonjululwe ngoJulayi 23 Ubuntu 19.04 esiza kuzichaza apha ngezantsi. Inguqulelo entsha, esiyikhumbulayo ikwabonakala kwiDisco Dingo, yiLinux 5.0.0-23.24 ~ 18.04.1 ye-Ubuntu 18.04 LTS kunye neLinux 5.0.0-23.24 ye-Ubuntu 19.04. Apha sikhumbula iincukuthu abazilungisileyo kwiveki ephelileyo eDisco Dingo nakwizolo eBionic Beaver.
I-kernel entsha ilungisa ezi bugs zine
- I-CVE-2019-11487: yafunyanwa Ukuphuphuma kwenani elipheleleyo bekukho kwi-kernel ye-Linux xa ubhekisa kumaphepha, kukhokelela kwimicimbi yokusebenziseka emva kokuba ikhutshiwe. Umhlaseli wasekhaya unokusebenzisa oku ukwenza ukwaliwa kwenkonzo (ukucima okungalindelekanga) okanye enze ikhowudi yokuchasana nomthetho.
- I-CVE-2019-11599: UJann Horn wafumanisa ukuba imeko yomdyarho ikho kwi-kernel ye-Linux xa kusenziwa inkunkuma. Umhlaseli wasekhaya unokusebenzisa oku ukwenza ukwaliwa kwenkonzo (inkqubo yengozi) okanye ukuveza ulwazi olubuthathaka.
- I-CVE-2019-11833: Ukuphunyezwa kwenkqubo yefayile ye-ext4 kwi-kernel ye-Linux kwafunyanwa kungavali imemori ngokufanelekileyo kwezinye iimeko. Umhlaseli wendawo unokusebenzisa oku ukubonisa ulwazi olubuthathaka (inkumbulo yenkozo).
- I-CVE-2019-11884: Ndifumene ukuba iProtokholi yoLuntu yeNkqubo yeBluetooth (HIDP) kwi-kernel yeLinux ayiqinisekisanga ngokuchanekileyo ukuba imitya yapheliswa NULL kwiimeko ezithile. Umhlaseli wendawo unokusebenzisa oku ukubonisa ulwazi olubuthathaka (inkumbulo yenkozo).
Canonical icebisa ukuvuselelwa ngokukhawuleza, ngakumbi abasebenzisi be-Ubuntu 18.04. Ngokwam, andazi ukuba kutheni besungule i Inguqulelo entsha ye-Ubuntu 19.04 kwaye oko akukabikho uluhlu lweendaba akuncedi ukushiya amathandabuzo. Kwimeko nayiphi na imeko kwaye njengamaxesha onke, kufanelekile ukuhlaziywa ngoku ngoku. Siyakhumbula ukuba ii-patches azisayi kusetyenziswa de siqale ikhompyuter.
