SV-37605r1_rule The Bluetooth protocol handler must be disabled or not installed.

Vulnerability discussion

Bluetooth is a Personal Area Network (PAN) technology. Binding this protocol to the network stack increases the attack surface of the host. Unprivileged local processes may be able to cause the kernel to dynamically load a protocol handler by opening a socket using the protocol.

Check content

Fix text

Prevent the Bluetooth protocol handler for dynamic loading. # echo "install bluetooth /bin/true" >> /etc/modprobe.conf

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.
