Ensure prelink is disabled

Details

prelink is 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.

Rationale:

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.

Solution

Run the following command to restore binaries to normal:

# prelink -ua

Run the following command to uninstall prelink:

# zypper remove prelink
