Title

The control script lists of preloaded libraries must contain only absolute paths on AIX systems. (Cat II impact)

Discussion

The library preload list environment variable contains a list of libraries for the dynamic linker to load before loading the libraries required by the binary. If this list contains paths to libraries relative to the current working directory, unintended libraries may be preloaded.

Check Content

Verify run control scripts' library preload list using command: # grep -r LDR_PRELOAD /etc/rc* /etc/rc.teboot:export LDR_PRELOAD=/../usr/bin /etc/rc.teboot:export LDR_PRELOAD=/usr/bin This variable is formatted as a colon-separated list of paths. If there is an empty entry, such as a leading or trailing colon, or two consecutive colons, this is a finding. If an entry begins with a character other than a slash (/) or other than "$PATH", it is a relative path, and this is a finding.

Fix Text

Edit the run control scripts' library preload list and remove relative paths.
