Lasse Collin, endine projekti xz hoidja, kes edastas \u00f5igused uuele hoidjale Jia Tanile 2022. aastal, mille tegevus viis tagaplaneeringu rakendamiseni, avaldas parandustooted pakettidele XZ Utils 5.2.13, 5.4.7 ja 5.6.2, milles eemaldati tagaplaneeringu komponendid ja muud kahtlased muudatused, mis olid lisatud eelneva hoidja pahatahtliku tegevuse t\u00f5ttu. <\/p>\n

Samuti avaldati \u00fclevaatearuande Git-i salvestusruumist ja muudatustest, mis lisati alates detsembrist 2022, kui Jia Tan oli hoidja ametis. Muudatused on anal\u00fc\u00fcsitud eraldi commit'ite tasandil. Repositooriumi commit'id ei olnud digitaalselt allkirjastatud, kuid esialgseid v\u00f5ltsimise m\u00e4rke commit'ide autorite seas ei leitud. \u00dchtekokku eemaldati repositooriumist 8 pahatahtlikku commit'i. <\/p>\n

CRC CLMUL kood, mis p\u00f5hjustab valeh\u00e4ireid MSAN-is (m\u00e4lu sanitaar), on j\u00e4tkuvalt \u00e4ra eemaldamata ja p\u00f5hjustab probleeme OSS Fuzziga. Edasi on kood plaanis \u00fcmber t\u00f6\u00f6tada, kuid praegu on otsustatud seda mitte puutuda, et v\u00e4ltida regressioone vanades harudes. Vanades commit'ides, mis on lisatud enne tagaplaneeringu edendamisega seotud muudatuste tegemist, kahtlaseid muudatusi ei leitud. Eraldi kontrolliti lokaliseerimise po-faile, tar-failide metaandmeid ja v\u00e4ljaandete ning t\u00f5lgete arhiive. <\/p>\n

Muudatustest m\u00e4rgitakse ka akumuleerunud vea paranduste lisamist ja IFUNC mehhanismi toe eemaldamist, mis on pakutud Glibc-sse funktsioonide kaudseks v\u00e4ljakutsumiseks, mida kasutati funktsioonide p\u00fc\u00fcdmise korraldamiseks tagaplaneeringus. On m\u00e4rgitud, et IFUNC-i kasutamine keerukendab koodi, samal ajal kui saavutus j\u00f5udluses on ebaoluline. Kaitsena eemaldati ka allika koodiga paketist XZ logo, PDF versioonid man-lehtedest ja kaks testi arhitektuuridele x86 ja SPARC, kus sisendandmetena t\u00f6\u00f6deldi objekti faile. <\/p>\n

Uute hulka kuulub xzdec dekooderisse lisatud tugi 4. versiooni ABI rakenduste isoleerimise mehhanismile Landlock. Autotools'i koostamisskriptidesse on lisatud valik «—enable-doxygen», ning Cmake'i skripti parameeter ENABLE_DOXYGEN API liblzma dokumentatsiooni genereerimise ja installimise jaoks Doxygeniga. Juba genereeritud dokumentatsioon on paketist eemaldatud.
