System-wide shared library files, which are linked to executables during process load time or run time, are stored in the following directories by default: /lib /lib64 /usr/lib /usr/lib64 Kernel modules, which can be added to the kernel during runtime, are also stored in '/lib/modules'. All files in these directories should be owned by the 'root' user. If the directory, or any file in these directories, is found to be owned by a user other than root correct its ownership with the following command: '$ sudo chown root FILE'


Parameter:

[Share_Lib_files_have_Root_Ownership/Share_Lib_files_does_not_have_Root_Ownership]


Technical Mechanism:

Files from shared library directories are loaded into the address space of processes (including privileged ones) or of the kernel itself at runtime. Proper ownership is necessary to protect the integrity of the system.
