1.206 OL09-00-002012

Information

OL 9 must prevent code from being executed on file systems that are imported via Network File System (NFS).

GROUP ID: V-271642
RULE ID: SV-271642r1092593

The "noexec" mount option causes the system not to execute binary files. This option must be used for mounting any file system not containing approved binary as they may be incompatible. Executing files from untrusted file systems increases the opportunity for nonprivileged users to attain unauthorized administrative access.

Solution

Update each NFS mounted file system to use the "noexec" option on file systems that are being imported via NFS.
