| 2 | # |
| 3 | # Description |
| 4 | # =========== |
| 5 | # prelink is a program that modifies ELF shared libraries and ELF dynamically |
| 6 | # linked binaries in such a way that the time needed for the dynamic linker to |
| 7 | # perform relocations at startup significantly decreases. |
| 8 | # |
| 9 | # Rationale |
| 10 | # ========= |
| 11 | # The prelinking feature can interfere with the operation of AIDE, because it |
| 12 | # changes binaries. Prelinking can also increase the vulnerability of the system |
| 13 | # if a malicious user is able to compromise a common library such as libc. |
| 14 | # |
| 15 | # Audit |
| 16 | # ===== |
| 17 | # Run the following command and verify prelink is not installed: |
| 18 | # |
| 19 | # # dpkg -s prelink |
| 20 | # |
| 21 | # Remediation |
| 22 | # =========== |
| 23 | # Run the following command to restore binaries to normal: |
| 24 | # |
| 25 | # # prelink -ua |
| 26 | # |
| 27 | # Run the following command to uninstall prelink : |
| 28 | # |
| 29 | # # apt-get remove prelink |
| 30 | # |
| 31 | parameters: |
| 32 | linux: |
| 33 | system: |
| 34 | package: |
| 35 | prelink: |
| 36 | version: removed |
