From 130c02ebef0f54988452007b6dd0f72b70138db8 Mon Sep 17 00:00:00 2001 From: Ben Hutchings Date: Thu, 16 Feb 2017 19:09:17 +0000 Subject: [PATCH] dccp: Disable auto-loading as mitigation against local exploits Forwarded: not-needed We can mitigate the effect of vulnerabilities in obscure protocols by preventing unprivileged users from loading the modules, so that they are only exploitable on systems where the administrator has chosen to load the protocol. The 'dccp' protocol is not actively maintained or widely used. Therefore disable auto-loading.
