    Package : openssl094
    Vulnerability : cryptographic weakness
    Problem type : remote
    Debian-specific: no
    CVE ID : CVE-2005-2969

    Yutaka Oiwa discovered a vulnerability in the Open Secure Socket Layer
    (OpenSSL) library that can allow an attacker to perform active
    protocol-version rollback attacks that could lead to the use of the
    weaker SSL 2.0 protocol even though both ends support SSL 3.0 or TLS
    1.0.

    The following matrix explains which version in which distribution has
    this problem corrected.

                    oldstable (woody) stable (sarge) unstable (sid)
    openssl 0.9.6c-2.woody.8 0.9.7e-3sarge1 0.9.8-3
    openssl 094 0.9.4-6.woody.4 n/a n/a
    openssl 095 0.9.5a-6.woody.6 n/a n/a
    openssl 096 n/a 0.9.6m-1sarge1 n/a
    openssl 097 n/a n/a 0.9.7g-5

    We recommend that you upgrade your libssl packages.

    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.
