Iphutha elibulalayo livela ku-Ubuntu 17.04 naku-16.10 login screen

Kulezi zinsuku sonke sizwile ngegciwane le-WannaCry noma i-ransomware, i-malware efake wonke umuntu nezinkampani zakhe enkingeni. Ku-Ubuntu akuyona inkinga noma kubasebenzisi bayo, kepha Ubuntu abuyazi kulezi zinhlobo zezinkinga futhi muva nje ukhombise inkinga enkulu yokuphepha.

Le nkinga enkulu ivumela noma yimuphi umuntu ngendlela ebonakalayo angakwazi ukufinyelela amaseshini ayimfihlo futhi ngaleyo ndlela afinyelele amafayela ayimfihlo nezinsizakusebenza zekhompyutha.

Ngenhlanhla le bug ku-LightDM isivele ilungisiwe futhi ukuvuselelwa kwakamuva kuzosivumela ukuthi siphephe futhi sivikeleke futhi. Kuyathakazelisa ukuthi le bug kuthinta kuphela izinhlobo 16.10 no-17.04, izinhlobo ezi-systemd. Futhi kubonakala sengathi amanye amaphakheji asetshenziswe kulolu shintsho ku-systemd yimbangela yalo mgodi wokuphepha.

Ngaphezu kwalokho, inkinga ayinzima njengakwezinye izinhlelo zokusebenza ngoba umsebenzisi kufanele abekhona phambi kwekhompyutha ukuze akwazi ukwenza lokhu kungena, okungukuthi, ukuhlukumeza ukude kwezokuphepha akunakwenzeka.

Isibuyekezo esilungisa le bug okwamanje siyasatshalaliswa, kepha uma ungakayitholi okwamanje noma awufuni ukuyifaka kepha ufuna ukufinyelela kubasebenzisi bezivakashi futhi, kufanele uhlele ifayela lokumiswa kwe-LightDM. Ngakho-ke sivula ukuphela bese sibhala okulandelayo:

sudo gedit /etc/lightdm/lightdm.conf

Futhi sibhala okulandelayo:

# Manually enable guest sessions despite them not being confined
# IMPORTANT: Makes the system vulnerable to CVE-2017-8900
# https://bugs.launchpad.net/bugs/1663157

Silondoloza ifayela bese siqala kabusha ikhompyutha ukuze izinguquko ziqale ukusebenza. Ngokungafani nezinye izinhlelo zokusebenza, Ubuntu noMphakathi wabo benza uhlelo olusebenzayo luwusizo futhi luphephile kuwo wonke umuntu futhi uma kunanoma iyiphi inkinga, izolungiswa ngokushesha ngokubuyekeza.
