    Package        : toolchain-source
    Vulnerability  : insecure temporary files
    Problem-Type   : local
    Debian-specific: yes
    CVE ID         : CAN-2005-0159
    
    Sean Finney discovered several insecure temporary file uses in
    toolchain-source, the GNU binutils and GCC source code and scripts.
    These bugs can lead a local attacker with minimal knowledge to trick
    the admin into overwriting arbitrary files via a symlink attack.  The
    problems exist inside the Debian-specific tpkg-* scripts.
    
    For the stable distribution (woody) these problems have been fixed in
    version 3.0.4-1woody1.
    
    For the unstable distribution (sid) these problems have been fixed in
    version 3.4-5.
    
    We recommend that you upgrade your toolchain-source 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.

      its next update.
