    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

    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

    apt-get upgrade
            will install corrected packages
    
    You may use an automated update by adding the resources from the
    footer to the proper configuration.
