Title

The AIX root accounts list of preloaded libraries must be empty. (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 the "LDR_PRELOAD" environment variable is empty or not defined for the "root" user using command: # env | grep LDR_PRELOAD If a path is returned, this is a finding.

Fix Text

Edit the "root" user's initialization files and remove any definition of "LDR_PRELOAD".
