Amaphutha ezokuphepha kuLinux imvamisa ambalwa futhi aqhele kakhulu, kepha isichibi esisanda kukhishwa yiCanonical sikhombisa ukuthi lokhu akuhlali kunjalo. Inkampani elawulwa uMark Shuttleworth ikhiphe isibuyekezo se-kernel se-Ubuntu 16.04 LTS (Xenial Xerus) elungisa izimbungulu ezingafika ezinhlanu ezitholwe ngabaphenyi abahlukahlukene bezokuphepha ku-4.4 kernel, inhlamvu ekhona ohlelweni lokusebenza olukhishwe yiCanonical eminyakeni emithathu eyedlule, ngo-Ephreli 3. Zonke izinhlobo ezisekelwe ku-Ubuntu nazo ziyathinteka inhlamvu efanayo.
Ukulungiswa sekuvele kukhona ku-Linux 4.15 HWE efaka Ubuntu 18.04 LTS, ngakho-ke okunye ukukhishwa kwezinyanga eziyisishiyagalolunye zokuphila, okungukuthi okungewona ama-LTS kubonakala kuthintekile nakho. Iqiniso ukuthi i-Canonical yenze kuphela lokhu kubuyekezwa ukuthi kutholakale kubasebenzisi abanesistimu yokusebenza ebucayi futhi abasathokozela ukusekelwa okusemthethweni. Ubuntu 9 izokujabulela ukwesekwa kuze kube ngu-Ephreli 14.04 kepha i-kernel yayo ayithinteki yi 5 amaphutha okukhulunywe ngaye kulesi sihloko.
Ubuntu 16.04 Kernel Update Fixes 5 Security Bugs
Izimbungulu ezinhlanu ezilungisiwe yilezi:
- El I-CVE-2017-18241- Ukuqaliswa kohlelo lwefayela le-F2FS kwehlulekile ukuphatha ngokungafanele inketho yokukhweza noflush_merge.
- I-CVE-2018-7740: ihlobene nephutha langaphambilini, kepha kulokhu ekulayisheni okuningi ekusetshenzisweni umabhebhana. Lokhu kanye nesiphazamisi sangaphambilini kungavumela umsebenzisi wendawo ononya ukuthi asebenzise ubungozi ngokuncisha insizakalo.
- El I-CVE-2018-1120 itholwe ohlelweni lwefayela ukuvuma futhi yavumela umsebenzisi onobungozi wendawo ukuvimba amathuluzi athile asetshenziselwa ukuhlola uhlelo lwefayela ukuvuma ukubika isimo sohlelo lokusebenza ngoba yehlulekile ukuphatha kahle izinqubo zemephu kuzinto zememori.
- I-CVE-2019-6133 ivumele umsebenzisi onobungozi wendawo ukuthi athole ukufinyelela ezinsizakalweni ezigcinwe ukugunyazwa.
- I-CVE-2018-19985 kungavumela umhlaseli osondele ngokomzimba ukuthi abangele ukuphahlazeka kohlelo.
I-Canonical uncoma ukuthi bonke abasebenzisi abathintekayo babuyekeze ngokushesha okukhulu enguqulweni ye-kernel 4.4 esivele itholakala kumakhosombe asemthethweni. Ngokwami, uma ngicabanga ukuthi zonke izimbungulu kufanele zixhashazwe ngumhlaseli wendawo, ngizobuyekeza maduzane, kepha nami angizukukhathazeka kakhulu. Nawe?
