Description
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. Paths starting with a slash (/) are absolute paths.

Check Text ( C-36000r3_chk )
Verify local initialization files have library search path containing only absolute paths. Procedure: NOTE: This must be done in the BASH shell. # cut -d: -f6 /etc/passwd \|xargs -n1 -IDIR find DIR -name ".*" -type f -maxdepth 1 -exec grep -H LD_LIBRARY_PATH {} \; 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 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.

Check Text ( C-36000r3_chk )

Verify local initialization files have library search path containing only absolute paths.
Procedure:

NOTE: This must be done in the BASH shell.

# cut -d: -f6 /etc/passwd |xargs -n1 -IDIR find DIR -name ".*" -type f -maxdepth 1 -exec grep -H LD_LIBRARY_PATH {} \;

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 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 (F-31253r1_fix)
Edit the local initialization file and remove the relative path entry from the library search path variable.
