Check: GEN002420
SUSE Linux Enterprise Server v11 for System z STIG:
GEN002420
(in versions v1 r12 through v1 r9)
Title
Removable media, remote file systems, and any file system not containing approved setuid files must be mounted with the nosuid option. (Cat II impact)
Discussion
The "nosuid" mount option causes the system to not execute setuid files with owner privileges. This option must be used for mounting any file system not containing approved setuid files. Executing setuid files from untrusted file systems, or file systems not containing approved setuid files, increases the opportunity for unprivileged users to attain unauthorized administrative access.
Check Content
Check /etc/fstab and verify the "nosuid" mount option is used on file systems mounted from removable media, network shares, or any other file system not containing approved setuid or setgid files. If any of these files systems do not mount with the "nosuid" option, it is a finding.
Fix Text
Edit /etc/fstab and add the "nosuid" mount option to all file systems mounted from removable media or network shares, and any file system not containing approved setuid or setgid files.
