Identify local initialization files that have library search paths: # cat /etc/passwd | cut -f 1,1 -d ":" | xargs -n1 -IUSER sh -c 'grep -l LDR_PRELOAD ~USER/.*' /root/.sh_history /home/doejohn/.profile /home/doejane/.profile For each file identified above, verify the search path contains only absolute paths: Note: This variable is formatted as a colon-separated list of paths. # cat <local_initilization_file> | grep -Ei 'ldr|preload' LDR_PRELOAD=/usr/lib If the paths listed have not been documented and authorized by the ISSO/ISSM, this is a finding. 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.
