Check: GEN006270

AIX 6.1 SECURITY TECHNICAL IMPLEMENTATION GUIDE: GEN006270 (in versions v1 r14 through v1 r10)

Title

The /etc/news/hosts.nntp 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 numbers of the files. Excessive permissions on the hosts.nntp 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 hosts.nntp file. # find / -type f -name hosts.nntp # aclget < hosts.nntp file > If extended permissions are enabled, the file has an extended ACL, this is a finding.

Fix Text

Remove the extended ACL from the hosts.nntp file. #acledit < hosts.nntp file >
