Title

The root account's 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. This variable is formatted as a space-separated list of libraries. Paths starting with (/) are absolute paths.

Check Content

Consult vendor documentation for the system's dynamic linker to determine what environment variables are used to configure the list of preloaded libraries. List the root user's environment variables. Procedure: # env Determine if the root account's list of preloaded libraries is empty. If it is not, this is a finding.

Fix Text

Empty the root account's list of preloaded libraries.
