SV-39258r1_rule The /etc/news/nnrp.access file must not have an extended ACL.

Vulnerability discussion

File system extended ACLs provide access to files beyond what is allowed by the mode numbers of the files. Excessive permissions on the nnrp.access file may allow unauthorized modification which could lead to Denial of Service to authorized users or provide access to unauthorized users.

Check content

Check the permissions of the file. # find / -name nnrp.access # ls -lL < nnrp.access > If extended permissions are enabled, this is a finding.

Fix text

Remove the extended ACL from the nnrp.access file. # acledit < nnrp.access >

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.
