Emahoreni ambalwa edlule sishicilele i-athikili ekhuluma ngalokho okwaziwa ngokuthi I-Lockdown, imodyuli entsha yokuphepha ezofika neLinux 5.4. Phakathi kwalokho okuzokwenziwa yile mojule kufanele sisize ekugwemeni ukwenziwa kwekhodi engenakuphikiswa. Isibonelo esichaza kahle ukubaluleka kwaso sifikile namuhla, kusukela ICanonical ilungise ukuba sengozini okuningana kanti ezinye zazo zingasetshenziselwa ukwenza ikhodi engenakuphikiswa, into ezoba nzima kakhulu ngemuva kokukhishwa kweLinux 5.4.
Sekukonke, balungisiwe Ukuba sengozini okungu-6 eqoqwe emibikweni emithathu: the I-USN-4142-1 ethinta Ubuntu 19.04, Ubuntu 18.04 kanye Ubuntu 16.04, the I-USN-4142-2 elifana nelangaphambilini kepha ligxile ku-Ubuntu 14.04 naku-Ubuntu 12.04 (zombili ngezinguqulo ze-ESM) naku-USN-4143-1, okuthinta izinhlobo ezintathu ezisakujabulela ukwesekwa okusemthethweni. Konke ukukhubazeka kubhalwe ukuphuthuma okuphakathi naphakathi.
Ukuba sengozini okuyisithupha okuchaza ukuthi kungani sinakekela iLockdown
Ukuba sengozini okulungisiwe kube okulandelayo:
- I-CVE-2019-5094: Ukuba sengcupheni kokusebenzisa ikhodi kuxhomeke ekusebenzeni kwefayela lesabelo le-E2fsprogs 1.45.3. Ukwahlukanisa okwakhiwe ngokukhethekile kwe-ext4 kungadala ukuthi kubhalelwe ngaphandle komkhawulo kunqwaba, okuholele ekusebenzeni kwekhodi. Umhlaseli Ungalimaza ukwahlukanisa ukuze usebenzise lobu bucayi.
- I-CVE-2017-2888: Ukuba sengcupheni kokuchichima kwenamba okusizwayo kukhona lapho kwakhiwa okusha Indawo ye-RGB ku-SDL 2.0.5. Ifayela elenzelwe ngokukhethekile lingadala inani eliphelele ukuchichima okuholela ekubekweni kwememori encane kakhulu engaholela kufayela le- Ukuchichima kwebhafa kanye nokusetshenziswa kwekhodi okungenzeka Umhlaseli anganikeza ifayela le- Ifayela lesithombe elenzelwe ngokukhethekile ukubangela lokhu kuba sengcupheni.
- I-CVE-2019-7635, I-CVE-2019-7636, I-CVE-2019-7637 y I-CVE-2019-7638: I-SDL (Simple DirectMedia Layer) efinyelela ku-1.2.15 no-2.x kuze kufike ku-2.0.9 ine- lUkufundwa okungaphezulu kwe-Blit1to4 okususelwa kuvidiyo / SDL_blit_1.c, SDL_GetRGB kuvidiyo / SDL_pixels.c, SDL_FillRect kuvidiyo / SDL_surface.c nakuMap1toN kuvidiyo / SDL_pixels.c.
Okokuqala kokungenhla kuthinta no-Ubuntu 19.10 Eoan Ermine, ngakho-ke ama-patches azokhishwa maduzane ngenguqulo ezokhishwa ngo-Okthoba 17. Ngemuva kokuthi izibuyekezo zifakiwe, kufanele uqale kabusha ikhompyutha yakho ukuze izinguquko ziqale ukusebenza. Futhi yize kungezona ukwehluleka okukhulu, I-Lockdown, Sizokulinda.
