SV-44952r1_rule All library files must not have extended ACLs.

Vulnerability discussion

Unauthorized access could destroy the integrity of the library files.

Check content

Verify system libraries have no extended ACLs. # ls -lL /usr/lib/* /usr/lib64/* /lib/* /lib64/* | grep "+ " If the permissions include a '+', the file has an extended ACL and has not been approved by the IAO, this is a finding.

Fix text

Remove the extended ACL from the file. # setfacl --remove-all /usr/lib/* /usr/lib64/* /lib/* /lib64/*

Pro Tips

Lavender hyperlinks in small type off to the right (of CSS class id, if you view the page source) point to globally unique URIs for each document and item. Copy the link location and paste anywhere you need to talk unambiguously about these things.

You can obtain data about documents and items in other formats. Simply provide an HTTP header Accept: text/turtle or Accept: application/rdf+xml.
