SV-29707r1_rule The system must prevent local applications from generating source-routed packets.

Vulnerability discussion

Source-routed packets allow the source of the packet to suggest routers forward the packet along a different path than configured on the router, which can be used to bypass network security measures.

Fix text

Edit /etc/opt/ipf/ipf.conf and add rules to block outgoing source-routed packets, such as: block out log quick all with opt lsrr block out log quick all with opt ssrr Reload the IPF rules. # ipf -Fa -A -f /etc/opt/ipf/ipf.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.
