Anders Kaseorg discovered that afuse, an automounting file system in user-space, did not properly escape meta characters in paths. This allowed a local attacker with read access to the filesystem to execute commands as the owner of the filesystem.

Package        : afuse
Vulnerability  : privilege escalation
Problem type   : local
Debian-specific: no
CVE Id(s)      : CVE-2008-2232
Debian Bug     : 490921

Anders Kaseorg discovered that afuse, an automounting file system
in user-space, did not properly escape meta characters in paths.
This allowed a local attacker with read access to the filesystem to
execute commands as the owner of the filesystem.

For the stable distribution (etch), this problem has been fixed in
version 0.1.1-1+etch1.

For the unstable distribution (sid), this problem has been fixed in
version 0.2-3.

We recommend that you upgrade your afuse (0.1.1-1+etch1) package.

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
sources.list as given below:

apt-get update
        will update the internal database
apt-get upgrade

You may use an automated update by adding the resources from the
footer to the proper configuration.
