1.5.4 Ensure prelink is disabled


prelinkis a program that modifies ELF shared libraries and ELF dynamically linked
binaries in such a way that the time needed for the dynamic linker to perform relocations
at startup significantly decreases.


The prelinking feature can interfere with the operation of AIDE, because it changes
binaries. Prelinking can also increase the vulnerability of the system if a malicious user is
able to compromise a common library such as libc.


Run the following command to restore binaries to normal:

# prelink -ua

Uninstall prelink using the appropriate package manager or manual installation:

# yum remove prelink

# apt-get remove prelink

# zypper remove prelink
