Check: GEN006310

SUSE Linux Enterprise Server v11 for System z STIG: GEN006310 (in versions v1 r12 through v1 r9)

Title

The /etc/news/nnrp.access file must not have an extended ACL. (Cat II impact)

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. # ls -lL /etc/news/nnrp.access If the permissions include a '+', the file has an extended ACL. If the file has an extended ACL and it has not been documented with the IAO, this is a finding.

Fix Text

Remove the extended ACL from the file. # setfacl --remove-all /etc/news/nnrp.access
