Synopsis:    Moderate: fuse security update
Issue Date:  2011-07-20
CVE Numbers: CVE-2010-3879


FUSE (Filesystem in Userspace) can implement a fully functional file system
in a user-space program. These packages provide the mount utility,
fusermount, the tool used to mount FUSE file systems.

Multiple flaws were found in the way fusermount handled the mounting and
unmounting of directories when symbolic links were present. A local user in
the fuse group could use these flaws to unmount file systems, which they
would otherwise not be able to unmount and that were not mounted using
FUSE, via a symbolic link attack. (CVE-2010-3879, CVE-2011-0541,
CVE-2011-0542, CVE-2011-0543)

All users should upgrade to these updated packages, which contain
backported patches to correct these issues.
