Detail
Synopsis A vulnerability in DavFS2 allows local users to gain root privileges. Background Description While the call to "modprobe" itself cannot be manipulated, a local authenticated user can set the "MODPROBE_OPTIONS" environment variable to pass a user controlled path, allowing the loading of an arbitrary kernel module. Impact Workaround An additional defense measure can be implemented by enabling the Linux kernel module signing feature. This assists in the prevention of arbitrary modules being loaded.
