Information

AlmaLinux OS 9 must mount /var/tmp with the noexec option.

GROUP ID: V-269328
RULE ID: SV-269328r1050210

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

Modify "/etc/fstab" to use the "noexec" option on the "/var/tmp" directory.
