    Package : unzip
    Vulnerability : directory traversal
    Problem-Type : local
    Debian-specific: no
    CVE Ids : CAN-2003-0282

    A directory traversal vulnerability in UnZip 5.50 allows attackers to
    bypass a check for relative pathnames ("../") by placing certain invalid
    characters between the two "." characters.

    For the stable distribution (woody) this problem has been fixed in
    version 5.50-1woody1.

    For the unstable distribution (sid) this problem will be fixed soon.

    We recommend that you update your unzip 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.
