Ikhuphe ingxelo entsha yenkqubo yokuprinta ye-CUPS 2.3

Emva kweminyaka emalunga nemithathu yokusekwa kokugqibela kwesebe elibalulekileyo le-CUPS, U-Apple ubhengeze ukumiliselwa kwenguqulelo entsha yenkqubo yokushicilela yasimahla ye-CUPS 2.3 (Inkqubo yesiqhelo yokuPrinta i-Unix), esetyenziswa kwiMacOS kunye nokunikezelwa kweLinux. Iindebe zilawula ngokupheleleyo kuphuhliso lwenkampani ye-Apple, ethi ngo-2007 ifunxe inkampani yeeMveliso zeSoftware elula, eqalwe yiCUPS.

Le nguqulo intsha yeCUPS ime ngokufika nelayisensi entsha okoko ilayisensi yekhowudi itshintshile ukusuka kwi-GPLv2 kunye ne-LGPLv2 ukuya kwi-Apache 2.0.

Ilayisensi ye-Apache 2.0 ikwachaza ngokucacileyo ukuhanjiswa kwamalungelo kubuchwephesha bokuthengisa kunye nekhowudi.

Iziphumo ezimbi zokutshintsha ilayisensi ukusuka kwi-GPL ukuya kwi-Apache kukuphulukana nokuhambelana kwelayisensi ngeeprojekthi ezikhutshwa kuphela phantsi kwelayisensi ye-GPLv2 (ilayisensi ye-Apache 2.0 yi-GPLv3 ehambelana kodwa i-GPLv2 ayihambelani).

Ukusombulula le ngxaki, ukongezwa okhethekileyo kwimvumelwano yelayisensi yekhowudi phantsi kwelayisensi yeGPLv2 / LGPLv2.

Yintoni entsha kwiCUPS

Ukongeza kutshintsho lwelayisensi kolu hlobo lutsha lwe-CUPS 2.3, sinokuyifumana loo nto Yongeze inkxaso yokusetha kwangaphambili kunye "nokugqiba" kwiitemplate zomsebenzi wokuprinta ye IPP Yonke indawo umthetho olandelwayo, obonelela ngezixhobo zokukhetha amandla umshicileli okhoyo kwinethiwekhi, ekuvumela ukuba ubone ubukho beeprinta, uthumele izicelo, kwaye wenze imisebenzi yoshicilelo, nokuba kungoku ngqo okanye kungumlamli.

Ukwenziwa kubandakanya into entsha ippeveprinter ngokumiliselwa kwe-IPP elula kuyo yonke indawo iseva, enokusetyenziselwa ukuvavanya isoftware yomthengi okanye ukuqhuba imiyalelo yomsebenzi ngamnye wokuprinta.

Ngexesha Umyalelo we-lpstat wokubonisa imeko yokulala uyenziwa imisebenzi emitsha yoshicilelo.

Kwakhona Inkxaso ye-HTTP Digest kunye nokuqinisekiswa kwe-SHA-256 kuyabonakaliswa Kwithala leencwadi libcups. Kananjalo nemithetho ekufuneka ithathele ingqalelo iimpawu zeLexmark E120n, Lexmark Optra E310, Zebra, DYMO 450 Turbo, Canon MP280, Xerox kunye neHP LaserJet P1102 USB abashicileli.

Ukulungiswa komngcipheko kwi-CVE-2019-8696 kunye ne-CVE-2019-8675 , ebangele ukuba ukugcwala komhlaba kubelwe ukuqhubekeka idatha engasebenziyo kwi-nondo_get_packed kunye ne -n1_get_type imisebenzi esetyenziswayo xa kusenziwa izicelo ze-SNMP.

Olunye utshintsho esinokuyifumana kolu khululo lutsha:

• Kumiliselo lweprotocol yokwabelana ngokufikelela kubashicileli beBonjour, ukusetyenziswa kwamagama e-DNS-SD kunikezelwa xa ubhalisa umshicileli kwinethiwekhi
• Wongeze amandla okubhala iifayile ze-ippserver kwi-ipptool eluncedo
• Inkxaso eyongeziweyo ye-MinTLS kunye ne-MaxTLS iinketho kwisikhokelo se-SSLOptions ukukhetha ukuba zeziphi iinguqulelo ze-TLS oza kuzisebenzisa
• Yongezwe inkxaso yomsebenzisi weAgentTokens ukuya ku "client.conf"
• Inkonzo ehlaziyiweyo yenkqubo ukuqhuba iikomityi
• Iqela le-lpoptions ngoku linakho ukusebenza nge-IPP Kuyo yonke indawo abashicileli abangafakwanga kwimigca yoshicilelo lwasekhaya
• Inkxaso echanekileyo yeeprinta zangaphambili zokuprinta zongezwe kwi-IPP Yonke indawo umqhubi
• Ukususwa kwezinto eziluncedo cupaddsmb kunye cupstestdsc.

Uyifaka njani i-CUPS 2.3 ku-Ubuntu nakwiziphumo?

Okwangoku le nguqulo intsha yeCUPS ayifumaneki ngaphakathi koovimba abagcina Ubuntu, kungathatha iintsuku ezimbalwa ukuba ihlaziywe kumajelo asemthethweni.

Nangona kwabo bafuna ukukhuthaza le nguqulo intsha Banokukhuphela ikhowudi yemvelaphi yokudityaniswa kwenkqubo.

Kule nto vula nje itheminali kwaye ubhale oku kulandelayo:

wget https://github.com/apple/cups/releases/download/v2.3.0/cups-2.3.0-source.tar.gz

Emva koko baya kukhupha iphakheji

tar xzvf cups-2.3.0-source.tar.gz

Sifaka isikhombisi esenziwe nge:

cd cups-2.3.0

Kwaye sinokudibanisa kunye:

./configure

make

make check

sudo make install

Ekugqibeleni kuya kufuneka uyiqale kwakhona inkonzo okanye qala inkqubo yakho ukuze inguqulelo entsha iphinde isebenze.
