Information

OL 9 must mount /dev/shm with the noexec option.

GROUP ID: V-271651
RULE ID: SV-271651r1091665

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

Solution

Configure OL 9 to mount /dev/shm with the noexec option.

Modify "/etc/fstab" to use the "noexec" option on the "/dev/shm" file system.
