sunrat Posted December 5, 2019 Share Posted December 5, 2019 I predict that will be fixed before you can count to Jack Robinson. No VPN here, and no "loose" setting in sysctl.conf either. I didn't see a way in either of those articles to actually test vulnerability. There is a setting commented out which is said to mitigate this if you uncomment: # Uncomment the next two lines to enable Spoof protection (reverse-path filter) # Turn on Source Address Verification in all interfaces to # prevent some spoofing attacks #net.ipv4.conf.default.rp_filter=1 #net.ipv4.conf.all.rp_filter=1 Quote Link to comment Share on other sites More sharing options...
securitybreach Posted December 5, 2019 Share Posted December 5, 2019 Well the vulnerability was found in the lab and there is no indication that it was ever used in the wild either. Also: Quote The research team is planning to publish a paper with an in-depth analysis of this vulnerability and its implications but only after finding an adequate workaround. BTW systemd was just updated on arch the same day that this came out (yesterday...12/04/19) Quote Link to comment Share on other sites More sharing options...
