Disable Prelink

Details

*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 command-# /usr/sbin/prelink -uato restore binaries to a normal, non-prelinked state, then remove prelink-# apt-get purge prelink
