Assessment Title

Rule Text

The root account's library search path must be the system default and must contain only absolute paths.

Description

Discussion Text

The library search path environment variable(s) contain a list of directories for the dynamic linker to search to find libraries. If this path includes the current working directory or other relative paths, libraries in these directories may be loaded instead of system libraries. This variable is formatted as a colon-separated list of directories. If there is an empty entry, such as a leading or trailing colon or two consecutive colons, this is interpreted as the current working directory. Entries starting with a slash (/) are absolute paths.

The reconstructed evaluation script behind this rule's OVAL check(s) — every module a compound check combines, with this rule's own concrete values and DISA's SCC tool's real per-module mechanism curated from static teardown of SCC releases.

Assessment Script Powered by AISandbox-executed

A standalone Shell script to assess this control automatically. Review before running it in your environment.

Syntax-checked and actually executed in an isolated sandbox (not the real system this checks) — confirmed to run without errors.

root_home=$(getent passwd root | cut -d: -f6)
if [ -z "$root_home" ]; then echo "PASS"; exit 0; fi
root_profile="$root_home/.profile"
if [ ! -f "$root_profile" ]; then echo "PASS"; exit 0; fi
if grep -q "^LD_LIBRARY_PATH=" "$root_profile"; then echo "FAIL"; exit 1; fi
echo "PASS"
exit 0

Remediation

Edit the root user initialization files and remove any definition of LD_LIBRARY_PATH.
