SV-64739r1_rule The system must use a separate file system for /tmp.

Vulnerability discussion

The "/tmp" partition is used as temporary storage by many programs. Placing "/tmp" in its own partition enables the setting of more restrictive mount options, which can help protect programs which use it.

Check content

Run the following command to determine if "/tmp" is on its own partition or logical volume: $ mount | grep "on /tmp " If "/tmp" has its own partition or volume group, a line will be returned. If no line is returned, this is a finding.

Fix text

The "/tmp" directory is a world-writable directory used for temporary file storage. Ensure it has its own partition or logical volume at installation time, or migrate it using LVM.

Pro Tips

Lavender hyperlinks in small type off to the right (of CSS class id, if you view the page source) point to globally unique URIs for each document and item. Copy the link location and paste anywhere you need to talk unambiguously about these things.

You can obtain data about documents and items in other formats. Simply provide an HTTP header Accept: text/turtle or Accept: application/rdf+xml.
