Subject: 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.
