There was a stupid error in patchfile davfs2-1.4.6-system.diff. It has been replaced by davfs2-1.4.6-system-2.diff.

davfs2 calls the function system() several times. When installed setuid root this may allow for privilege escalation.

The patches will fix this vulnerability for versions 1.4.6 and 1.4.7.

As a side effect davfs2 will no longer try to insert needed kernel modules or create the device special files /dev/fuse or /dev/codaX. So you have to make sure that one of these devices exists before mounting a davfs2 file system. On most systems /dev/fuse should exist by default.
