The prelinking feature changes binaries in an attempt to decrease their startup time.
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.
Fix:
Run the command:
# /usr/sbin/prelink -ua to restore binaries to a normal, non-prelinked state, then remove prelink:
# apt-get purge prelink
Parameter:
[yes/no]
Technical Mechanism:
Run the command:
# /usr/sbin/prelink -ua to restore binaries to a normal, non-prelinked state, then remove prelink:
# apt-get purge prelink
