A xz project repository continues to show changes made by the backdoor author to block protection mechanisms. A change was detected in the CMakeLists.txt assembly script that prevented the use of the Landlock application isolation mechanism when supported by the system. In the C code checking the availability of the Landlock system call, an extra dot was intentionally added, causing the Landlock availability check to fail under all conditions. <\/p>\n
