## Description

mountall.c in mountall before 2.15.2 uses 0666 permissions for the
root.rules file, which allows local users to gain privileges by modifying
this file.

### From the Ubuntu Security Team

Alasdair MacGregor discovered that mountall created a udev rule file
with world-writable permissions. A local attacker could exploit this
under certain conditions to cause udev to execute arbitrary commands as
the root user.

luckily, udev doesn't use inotify on this directory at boot time, so
udev needs to be reloaded before this is really ugly.
