Zvekare zvakare, isu tinofanirwa kutaura nezvazvo kernel chengetedzo zvikanganiso, asi zvakare zvakare tinoshuma kana Canonical yatovagadzirisa. Pakazara, nhamo nhatu dzakawanikwa uye dzakatochekwa kare, imwe yacho yakanyorwa neCanonical seinonyanya kukosheswa, nepo mamwe maviri akanyorwa seakakosha pakati. Kwese kusasimba kwechitatu kunokanganisa zvese shanduro dzeUbuntu, kusanganisira Ubuntu 19.04, Ubuntu 18.04 LTS, uye Ubuntu 16.04 LTS.
Canonical yakaburitsa mishumo miviri pane izvi zvitatu zvinokuvadzwa, the USN-4135-1 mavanotitaurira pamusoro peUbuntu shanduro dzichiri kunakidzwa nerutsigiro rwepamutemo uye iyo USN-4135-2 iyo inotaura nezvechinhu chimwe chete ichocho, asi yeUbuntu 14.04 uye Ubuntu 12.04 ayo parizvino ari ESM (Yakawedzerwa Kuchengetedzwa Kwekuchengetedza) vhezheni. Izvo zvisati zvatemwa kunze kwekuti bug yakakomba yevatatu inobata Ubuntu 19.10 Eoan Ermine.
Iyo kernel nyowani inogadzirisa izvi zvitatu kushushikana
- CVE-2019-14835: yakawanikwa buffer inopfachukira mu backend (vhost_net) kuitiswa kweiyo virtio network muLinux kernel. Anorwisa muenzi anogona kushandisa izvi kukonzera kuramba kwebasa (inomiririra OS kupunzika) kana kuitisa kodhi yekumanikidza pane iyo inomiririra OS (yakanyanya kukoshesa).
- CVE-2019-15030:eIyo Linux kernel pazvivakwa zvePowerPC haina kubata zvakakwana Sisitendi Isingawanikwe kunze kwemamwe mamiriro. Anorwisa wemunharaunda anogona kushandisa izvi kufumura ruzivo rwakashata (pakati pekutanga).
- CVE-2019-15031: iyo Linux kernel pazvivakwa zvePowerPC haina kubata zvakakwana kukanganiswa kusarudzika mune mamwe mamiriro. Anorwisa munharaunda anogona kushandisa izvi kuburitsa pachena ruzivo
Mune ma link apfuura, iwe une ruzivo rwese nezve mapakeji ayo anofanirwa kuvandudzwa, asi chaizvo isu tinofanirwa kuvhura yedu software yekuvandudza uye gadza zvese zvatinoona se "linux-". Kana mapakeji ese aiswa, isu tinofanirwa kutangazve kuti shanduko dziite.
