Ngaphandle kokungabaza, izindaba ezibaluleke kakhulu esizoshicilela namuhla ukuthi iCanonical ikhiphe Ubuntu 19.10 Eoan Ermine. Ukuthi siyalazi igama lohlelo lelo izokwethulwa ezinyangeni eziyisithupha noma ukuthi balungisile ukuba sengozini okuhlukahlukene ku-Ubuntu kernel kuzoba ngemuva. Kepha ngeke sime ngokulinda, i-blogosphere akumele ime, futhi lokhu okwenzekile emahoreni ambalwa edlule.
Sekukonke, inguqulo entsha ye-kernel inayo kulungiswe ubungozi obungu-9 eqoqwe embikweni I-USN-4157-1. Ngesikhathi salokhu kubhalwa, okuwukuphela kohlelo lokusebenza oluthintekile abalushoyo yi-Ubuntu 19.04, kepha ezinye izimbungulu zimakwe njengezi "zilindile" ku-Ubuntu 18.04 naku-Ubuntu 16.04. Kuwo wonke amacala ayisishiyagalolunye, Ubuntu 19.10 ubhalwe njengo "ongathinteki".
U-Eoan Ermine kernel akathinteki
Ukwehluleka, okubhalwe njengokubalulekile okuphansi noma okuphakathi, kungokulandelayo:
- I-CVE-2019-14814, I-CVE-2019-14815 y I-CVE-2019-14816: umshayeli wedivayisi ye-Marvell Wi-Fi ku-kernel ye-Linux ubengasebenzisi ukuhlolwa kwemikhawulo kahle, okudala ukugcwala kwenqwaba. Umhlaseli wendawo angasebenzisa lokhu ukudala ukwenqatshwa kwensiza (system hang) noma enze ikhodi engafanele.
- I-CVE-2019-14821: lUkuqaliswa kwe-KVM hypervisor ku-Linux kernel akuzange kuhlole kahle umngcele lapho kusingathwa imisebenzi yokubhala ehlanganisiwe ye-MMIO. Umhlaseli wendawo onokufinyelela kokubhala ku / dev / kvm angasebenzisa lokhu ukudala ukunqatshelwa kwensiza (system hang).
- I-CVE-2019-15504- Umshayeli we-Wi-Fi 91x ku-kernel ye-Linux akazange azisingathe kahle izimo zephutha lokuqalisa, okuholele ekubeni sengozini ephindwe kabili. Umhlaseli oseduze angakusebenzisa lokhu ukudala ukwenqatshwa kwensiza (system hang).
- I-CVE-2019-15505: the Umshayeli wedivayisi yeTechnisat DVB-S / S2 USB ku-Linux kernel ibinokugcwala kakhulu kwe-buffer. Umhlaseli oseduze angakusebenzisa lokhu ukudala ukwenqatshwa kwensizakalo (ukuphahlazeka kwesistimu) noma aveze imininingwane ebucayi.
- I-CVE-2019-15902: wenaUkunciphisa i-Specter kwasetshenziswa ngokungafanele ku-Linux kernel ptrace subsystem. Umhlaseli wendawo angasebenzisa lokhu ukudalula imininingwane ebucayi.
- I-CVE-2019-16714: lUkuqaliswa kwe-IPv6 RDS ku-Linux kernel bekungaqali kahle izinkambu kusakhiwo sedatha ebuyiselwe esikhaleni somsebenzisi. Umhlaseli wendawo angasebenzisa lokhu ukudalula imininingwane ebucayi (inkumbulo ye-kernel). Khumbula ukuthi umthetho olandelwayo we-RDS uvinjelwe ku-Ubuntu ngokuzenzakalela.
- I-CVE-2019-2181Ukuchichima kwenani eliphelele bekukhona ekusetshenzisweni kwe-Linux kernel kwe-Binder, okuholele ekuchichimeni kwesibha Umhlaseli wendawo angasebenzisa lokhu ukukhulisa amalungelo.
Buyekeza manje
Ukuvuselelwa sezivele zitholakala ezikhungweni ezahlukahlukene zesoftware (noma kuhlelo lokusebenza lokubuyekeza) lwawo wonke ama-flavour asemthethweni we-Ubuntu. Uma usufakiwe, uzodinga ukuqala kabusha ikhompyutha yakho ukuze ushintsho luqale ukusebenza.
