Lasse Collin, endine xz projekti hooldaja, kes andis 2022. aastal \u00f5igused \u00fcle uuele hooldajale Jia Tanile, kelle tegevus viis tagaukse rakendamiseni, avaldas parandavad v\u00e4ljaanded paketist XZ Utils 5.2.13, 5.4.7 ja 5.6.2, kust on eemaldatud tagaukse komponendid ja muud kahtlased muudatused, mis olid lisatud eelmise hooldaja kuritegeliku tegevuse tulemusena. <\/p>\n

Lisaks on avaldatud aruanne Git-repositooriumi ja muudatuste \u00fcle, mis lisati alates 2022. aasta detsembrist Jia Tani hooldajaks olemise ajal. Muudatused on anal\u00fc\u00fcsitud \u00fcksikute commit'ide tasandil. Repositooriumi commit'id ei olnud digitaalsete allkirjadega kinnitatud, kuid pettuse j\u00e4lgi commit'ide autorite seas ei leitud. Kokku on repositooriumist eemaldatud 8 pahatahtlikku commit'i. <\/p>\n

Koodibaasist ei ole veel eemaldatud CRC CLMUL kood, mis p\u00f5hjustab valeh\u00e4ireid MSAN-is (Memory Sanitizer) ja probleeme OSS Fuzziga. Edasi plaanitakse see kood \u00fcmber t\u00f6\u00f6tada, kuid hetkel on otsustatud sellega mitte tegeleda, et v\u00e4ltida regressioone vanades harudes. Kahtlasi muudatusi vanades kommitites, mis on tehtud enne tagaukse edendamisega seotud muudatuste tegemist, ei leitud. Eraldi kontrolliti lokaliseerimise po-faile, metainformatsiooni tarfailides ja v\u00e4ljaandeid ning t\u00f5lkeid. <\/p>\n

Muudatuste seas on m\u00e4rgitud ka akumuleerunud vea paranduste kaasamine ning IFUNC mehhanismi toetuse eemaldamine, mida Glibc pakub funktsioonide kaudseks kutsumiseks, mis oli seotud funktsioonide \u00fcleminekute korraldamisega tagaukses. M\u00e4rgitud on, et IFUNCi kasutamine ainult keerukendab koodi, samas kui sellest saadav j\u00f5udluse kasu pole oluline. Ohutuse tagamiseks on ka allikakoodiga paketist eemaldatud XZ logo, PDF versioonid man-lehtedest ja kaks testimist x86 ja SPARC arhitektuuride jaoks, kus sisendandmeteks olid objektifailid. <\/p>\n

Uudistustest on xzdec dekooderisse lisatud toetus 4. versiooni ABI rakenduste isoleerimise mehhanismile Landlock. Autotools'i ehitusskriptidesse on lisatud valik «—enable-doxygen», samas kui Cmake'i skriptis on parameeter ENABLE_DOXYGEN API liblzma dokumentatsiooni genereerimiseks ja installeerimiseks Doxygeniga. Juba genereeritud dokumentatsioon on pakist eemaldatud.
