Package        : loop-aes-utils
Vulnerability  : programming error
Problem type   : local
Debian-specific: no
CVE Id(s)      : CVE-2007-5191

It was discovered that loop-aes-utils, tools for mounting and manipulating
filesystems, didn't drop privileged users and groups in the correct order
in the mount and umount commands.  This could potentially allow a local
user to gain additional privileges.

For the stable distribution (etch), this problem has been fixed in version
2.12r-15+etch1.

For the old stable distribution (sarge), this problem has been fixed in
version 2.12p-4sarge2.

We recommend that you upgrade your loop-aes-utils 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
        will install corrected packages

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