Package        : synaesthesia
Vulnerability  : insecure file creation
Problem-Type   : local
Debian-specific: no
CVE Ids        : CAN-2004-0160

During an audit, Ulf Harnhammar discovered a vulnerability in
synaesthesia, a program which represents sounds visually.
synaesthesia created its configuration file while holding root
privileges, allowing a local user to create files owned by root and
writable by the user's primary group.  This type of vulnerability can
usually be easily exploited to execute arbitary code with root
privileges by various means.

For the current stable distribution (woody) this problem has been
fixed in version 2.1-2.1woody1.

The unstable distribution (sid) is not affected by this problem, because
synaesthesia is no longer setuid.

We recommend that you update your synaesthesia 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.
