Debian Bug     : 567633

Dan Rosenberg discovered a race condition in FUSE, a Filesystem in USErspace.
A local attacker, with access to use FUSE, could unmount arbitrary
locations, leading to a denial of service.


For the oldstable distribution (etch), this problem has been fixed in
version 2.5.3-4.4+etch1.

For the stable distribution (lenny), this problem has been fixed in
version 2.7.4-1.1+lenny1.

For the unstable distribution (sid), this problem has been fixed in
version 2.8.1-1.2, and will migrate to the testing distribution (squeeze)
shortly.

We recommend that you upgrade your fuse packages.

Upgrade instructions
- --------------------

wget url
        will fetch the file for you
dpkg -i file.deb
        will install the referenced file.

If you are using the apt-get package manager, use the line for
